The practical difference is in the surrounding hardware and software: the ESP32-S3 provides USB-OTG plus USB-Serial/JTAG on a shared integrated PHY, while the Pico routes RP2040 USB to a micro-USB connector and supports its ROM USB bootloader through that port. Choose by the USB role and class your project needs, then verify the specific board’s wiring and host power.

What “USB 2.0” and “USB 1.1” mean here
The labels are not a reason to assume that the ESP32-S3 offers USB high-speed data transfer. Espressif says the S3 USB-OTG peripheral supports full-speed mode; Raspberry Pi describes RP2040 USB as USB 1.1. For this comparison, treat both as full-speed choices and confirm that this meets the peripheral’s requirements. The cited documentation does not provide a controlled throughput comparison between boards.

USB role and USB speed are separate questions. A controller may support host and device roles while still operating at full speed. Neither board should be selected on the assumption of 480 Mbit/s USB high-speed capability.
ESP32-S3: OTG, Serial/JTAG, and the shared PHY
Host and device roles
Espressif says ESP32-S3 USB-OTG supports both host and device functions. Its USB FAQ documents HID and mass-storage examples, and the ESP-IDF v6.0 USB device-stack documentation includes a TinyUSB MIDI example. These are documented paths, not a promise that every class works in every framework or release.

USB-Serial/JTAG is useful, but not an independent second connector
The S3 also has USB-Serial/JTAG for firmware download and debugging. However, Arduino-ESP32 documents that USB-OTG and USB-Serial/JTAG share the integrated PHY. The presence of both functions therefore does not mean both can automatically operate at once through the same PHY and board connection. The Arduino-ESP32 USB Host API specifically warns against choosing USB-OTG TinyUSB mode while also enabling USB CDC on boot.

Check the framework’s USB mode and CDC-on-boot settings alongside the board schematic. If the project needs both application USB and a development/debug connection, establish how the exact board exposes those paths before committing to its wiring or workflow.
Raspberry Pi Pico: one USB port, two possible roles
RP2040 has an integrated USB 1.1 PHY and controller that Raspberry Pi says can be used in either device or host mode. On the Pico board, USB is routed to a standard micro-USB port, with two required external 27-ohm resistors. The port can be used by application code or to access the ROM USB bootloader in BOOTSEL mode.

Raspberry Pi also lists drag-and-drop programming using USB mass storage. That is a firmware-loading workflow; it should not be confused with a guarantee that every application USB role or class is available through every framework.
For host projects, do not infer from RP2040’s chip-level capability that every Pico-family board supplies a convenient powered host port. The cited Pico datasheet establishes the port and USB circuitry, but the exact host connector, wiring, and VBUS supply arrangement still need to match the build.

Host projects: verify VBUS power on the actual board
A USB host generally needs to provide bus power to a peripheral. A chip-level host feature alone does not establish that a development board can safely supply the required VBUS power. Check the board’s connector and routing, the host power switch or circuit, the source of power, and the peripheral’s current needs.
Espressif’s ESP32-S3-USB-OTG is a useful concrete example, not a guarantee about all ESP32-S3 boards: its user guide maps the host and device interfaces, describes selectable host-interface power sources, and specifies a 500 mA current-limiting circuit. For a Pico or another carrier board, inspect that board’s documentation rather than transferring this example’s power details to it.

Choose by project requirements, not chip name
Pick the ESP32-S3 when its USB and development features fit
- Your design needs USB host or device mode and the chosen framework documents support for its peripheral class.
- You want USB-Serial/JTAG for download or debugging and have checked how its shared PHY affects the application USB mode.
- You have selected a board whose connector, routing, and host VBUS power circuit suit the peripheral.
- Integrated wireless is relevant to the wider project; confirm the specific ESP32-S3 board’s features separately.
Pick the Pico when its board and firmware workflow fit
- Your project can use RP2040 USB at the documented USB 1.1 capability and full-speed operation.
- The Pico’s micro-USB connection and BOOTSEL ROM bootloader suit your development workflow.
- Your host design accounts for the exact board’s wiring and how VBUS power will be supplied.
- You have verified that the framework or library for your intended USB class supports RP2040 in the role you need.
Check these points before ordering or wiring
- Write down the role: host, device, or both at different times. Confirm that the board and selected software support that role.
- Name the USB class: for example, HID, CDC serial, mass storage, or MIDI. Verify class support in the exact framework release you will build against.
- Confirm speed: both options in the cited documentation are full-speed choices; do not assume high-speed USB.
- Inspect the board, not just the chip: check connector type, signal routing, whether the port is shared with programming/debug, and any PHY or mode constraints.
- For a host, plan power: verify the VBUS source and board circuit against the peripheral’s requirements.
- Confirm the workflow: decide whether you need a ROM bootloader, drag-and-drop loading, USB-Serial/JTAG, or a separate debug connection.
What the published specifications do not settle
The cited documentation does not establish a controlled comparison of real-world throughput or reliability, a complete USB-class parity matrix across current frameworks, or a universal host-power guarantee for all boards based on either chip. For a specific build, the decisive details are the board revision, USB wiring, VBUS supply, framework release, and peripheral class.
