The most capable all-in-one option is the Waveshare ESP32-S3-ePaper-1.54 board, which combines a 1.54-inch display with Wi-Fi, Bluetooth, a real-time clock, an SHTC3 temperature-and-humidity sensor, storage, USB, expansion interfaces, and audio circuitry. A separate SPI e-paper module is better when you already own an ESP32 and want to add a display.
The important qualification is that “1.54-inch” does not identify one universal screen. The integrated board is documented as 200 × 200 pixels, while Waveshare’s separate 1.54inch e-Paper (E) module is 240 × 240. Panel type, controller, revision, voltage, wiring, and example code all depend on the exact product.

Waveshare’s integrated board puts an ESP32-S3 microcontroller and the display on one development board. Its documented features include Wi-Fi and Bluetooth, a real-time clock (RTC), an SHTC3 temperature-and-humidity sensor, a TF card slot, USB, expansion interfaces, a microphone and audio codec circuitry, and a speaker header. The product documentation also identifies V1 and V2 revisions and warns that their example programs are not interchangeable. Confirm the revision printed on your board before copying a tutorial or downloading a sample from the ESP32-S3-ePaper-1.54 documentation.

The integrated board’s display is specified as 200 × 200 pixels. Some variants may differ in options such as touch, battery provision, or other board details, so read the exact product listing and schematic rather than assuming every board in the family has the same peripherals.
Standalone 1.54-inch SPI module
The separate 1.54inch e-Paper (E) module is a display product for use with an external controller such as an ESP32 board you already own. It is available as a driver-board version or a raw panel and uses 3-wire or 4-wire SPI. Its documented resolution is 240 × 240 pixels, not 200 × 200. Other 1.54-inch modules can have different monochrome or multicolor characteristics, so check the complete part number, controller, logic voltage, connector, and color mode before wiring it.
| Option | Documented display | Built-in capabilities | Best fit | Checks before purchase |
|---|---|---|---|---|
| Integrated ESP32-S3-ePaper-1.54 | 200 × 200 pixels | Wi-Fi, Bluetooth, RTC, SHTC3 sensor, TF card slot, USB, expansion, audio circuitry | A first build or a self-contained device using several onboard features | V1 or V2 revision, touch or non-touch variant, battery inclusion, and matching examples |
| Standalone 1.54-inch SPI module | 240 × 240 pixels for the documented E module | Display and driver electronics only on the driver-board version; raw-panel version requires more hardware | Adding e-paper to an existing ESP32 project | Raw panel versus driver board, exact controller, SPI wiring, voltage, color, and library support |
Use the product documentation for the exact pinout and initialization sequence. A display that looks identical can still require different commands or wiring.

E-paper is most useful when information can remain visible between updates. Waveshare describes these displays as retaining their image after power is removed and operating without a backlight; that makes them a natural match for static labels, occasional readings, and low-interaction information panels. It does not, by itself, establish a specific battery runtime.
Desk clock and status card
Use the integrated board’s RTC to keep time locally and Wi-Fi to synchronize or retrieve selected information. A useful layout might show a large time, date, a small connection indicator, and one or two values such as room temperature or a calendar item. Because the content can remain on screen, the firmware can wake periodically, update the page, and return to a low-activity state instead of redrawing continuously.

For a standalone module, the ESP32 supplies the timekeeping and network logic. Add an RTC or obtain time over the network if the project must keep time while disconnected.
Temperature-and-humidity display
The integrated board’s SHTC3 gives this project a direct hardware path. Read the sensor, format the values, and render a compact screen with the latest reading and an optional comfort label or short history. Treat the values as device readings, not laboratory measurements: the documentation establishes the presence of the sensor, not accuracy testing for your enclosure or placement.
Recommended Free Tools
Wi-Fi dashboard or electronic label
The ESP32-S3 can receive information over Wi-Fi and present a small summary: a server state, a queue count, a selected feed, or a changing label. The board is described for IoT terminals and electronic tags, so this is a sensible architectural use. Keep the first version narrow: fetch one data source, display a timestamp and an error state, and define what appears when the network is unavailable.
For a store-room or workshop label, the device can show an item name, revision, handling note, or last-updated time. A static label does not need frequent refreshes, which suits e-paper better than animation.
Portable note device, badge, or QR card
A compact screen can hold a short note, contact card, event badge, or QR code. The TF card slot on the integrated board offers a place to store assets or text, while Wi-Fi can provide a way to update selected content. Design the QR code with sufficient contrast and quiet space around it, and test it at the intended viewing distance; the display’s small physical size limits how much information can be packed into one code.

Waveshare’s resources page lists independent community projects including a minimalist AI note device, a QR-code wallet, a watch, and e-reader firmware. Those are examples of what developers have attempted, not features that arrive preinstalled on every board. See the official resources and community showcase for the project references.
Wireless Morse or compact handheld interface
A Morse trainer can display the current character, timing mode, and decoded message while sending input over Wi-Fi or Bluetooth. The same interaction pattern works for a small checklist, menu, or field data-entry terminal. You will need to provide controls—buttons, a keypad, touch hardware if your variant includes it, or an external input device—and implement the interaction logic yourself.
Audio or voice experiment
The integrated board includes microphone and audio codec circuitry plus a speaker header. That enables experiments such as recording a short clip, displaying a transcription status, playing a prompt, or showing a voice-controlled menu. Describe this as a development platform rather than a turnkey voice assistant: microphone placement, codec configuration, software, storage, networking, and power management remain your responsibility.
Simple monitor, HUD, watch, or e-reader interface
The community showcase also lists a monitor, HUD, watch, and e-reader firmware. These examples suggest several interface patterns: a glanceable page with a few metrics, a wearable-style status screen, or paginated text. E-paper can make those pages readable in ambient light, but page turns and redraws are not equivalent to video playback.
How to choose between the integrated board and a separate module
Choose the integrated board when you want the RTC, SHTC3, wireless networking, storage, or audio hardware without designing those interfaces yourself. It is also the simpler starting point for a first prototype because the display and controller are already assembled.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
Choose the standalone module when an ESP32 is already part of your design, when you need the documented 240 × 240 canvas of the E module, or when your enclosure and power system are built around a separate controller. The raw-panel version is a more advanced choice because it does not provide the same driver-board convenience.
- Verify the exact resolution and color mode instead of relying on the 1.54-inch diagonal measurement.
- Confirm whether you are buying a raw panel or a module with a driver board.
- Match the logic voltage and SPI wiring to the display’s documentation.
- Check that the software example targets your controller, display family, and board revision.
- If you need a battery, verify that the specific integrated-board variant includes the relevant connector or battery hardware.
A reliable build workflow
- Identify the hardware. Record the full product name, display resolution, controller, board revision, and whether the unit is integrated, driver-board based, or a raw panel.
- Open the matching documentation. Start with the integrated-board guide or the standalone E-module overview. Do not substitute a similarly named 1.54-inch product.
- Select a supported development framework. The integrated board supports Arduino IDE and ESP-IDF. Install the board support and dependencies specified by the current documentation, then select the correct target before compiling.
- Run the matching display example first. Use an official example for your revision and confirm that the screen initializes, draws an image, and completes a refresh before adding sensors, networking, or audio.
- Add one feature at a time. For example, draw a clock page, then read the SHTC3, then add Wi-Fi synchronization. This isolates display, sensor, and network failures.
- Define failure states. Show a stale-data timestamp, a disconnected indicator, or a readable error page instead of leaving a blank screen when a network request or sensor read fails.
- Measure the update schedule in the finished enclosure. Your battery, radio activity, sleep settings, image size, and refresh frequency determine practical endurance; do not infer runtime from the display’s diagonal size.
An additional board-specific software example is available in the Espressif Component Registry at tuanpmt/esp_epaper version 2.0.0. Treat any pinout or configuration in that example as applicable to the named board and version, not as a universal recipe for every 1.54-inch panel.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Designing around e-paper’s update behavior
Use periodic updates, not continuous animation
E-paper is suited to a clock that changes once per minute, a sensor card that updates every few minutes, or a label that changes when an item is edited. It is a poor fit for a camera viewfinder, game with rapid motion, or continuously animated dashboard. Frequent full-screen updates can introduce visible flashing and consume more energy than a mostly static design.
Understand the published refresh and power figures
For the documented 1.54inch e-Paper (E) product, Waveshare publishes a 27-second full-refresh time and refresh power consumption under 40 mW. These are model-specific published specifications, and the same page cautions that actual refresh time and consumption can vary. Do not apply those numbers to the integrated 200 × 200 board or to another panel revision without evidence.
Plan for retained images and stale information
The screen can retain its displayed content after power is removed, which is useful for labels and last-known readings. It also means a viewer may see old information when the controller is asleep or disconnected. Put a timestamp or “last updated” field on network-fed pages, and clear or replace sensitive content deliberately before handing the device to someone else.
Best Value

Treat battery life as a system property
No single runtime figure applies to all builds. The full board, battery capacity, firmware sleep strategy, Wi-Fi and Bluetooth use, sensor sampling, audio activity, and update schedule all matter. A design that refreshes once an hour can have very different endurance from one that keeps a radio connection active and redraws frequently.
Common pitfalls and recovery steps
The example compiles but the display stays blank
- Recheck whether the board is V1 or V2; Waveshare states that examples are not interchangeable.
- Confirm that the selected example matches 200 × 200 integrated hardware or the exact standalone module resolution.
- For a separate module, verify SPI mode, chip-select and control wiring against its manual, and check logic voltage.
- Run the vendor’s minimal initialization example before adding application code.
The image is distorted, shifted, or the colors are wrong
- Use the driver and lookup tables intended for the exact controller and panel variant.
- Check whether the product is monochrome or multicolor; a library for another color mode may produce unusable output.
- Confirm image dimensions and rotation in software. A 240 × 240 buffer is not interchangeable with a 200 × 200 buffer.
Network data is missing
- Display connection state and the time of the last successful update.
- Test the display and sensor without Wi-Fi, then test a simple network request before integrating the full dashboard.
- Keep the previous valid page visible when a request fails, but label it as stale.
The device drains its battery quickly
- Count radio-on time, sensor sampling, audio use, and refresh frequency separately.
- Reduce unnecessary full-screen refreshes and choose a slower polling interval where the application allows it.
- Measure current on the completed hardware; published figures for one display module do not describe the entire ESP32 system.
How far can you extend the basic build?
Once the display, input, and update loop work, the same platform can combine several roles. A desk clock can add humidity and a network status icon. A QR badge can retrieve a new code over Wi-Fi and store the last valid image on the TF card. A Morse terminal can log messages and play audio feedback. A field label can show a sensor value, a timestamp, and a warning state while spending most of its time idle.
Keep the user interface deliberately small. A 1.54-inch screen rewards one clear page, strong hierarchy, and short labels. Put detailed history or configuration behind a button, web page, or serial console rather than trying to display everything at once.
Bottom line
The best projects for a 1.54-inch ESP32 e-paper display are glanceable devices that update occasionally: clocks, sensor cards, labels, badges, compact dashboards, notes, and simple handheld tools. The integrated ESP32-S3-ePaper-1.54 board is the convenient route when its wireless, RTC, SHTC3, storage, and audio features match your design. A separate SPI module makes more sense when you already have an ESP32 or need a different panel configuration. Start by identifying the exact revision and display variant, run the matching example, and design around retained images and periodic updates rather than real-time animation.
