ℹ️ About RP2040 / RP2350 Firmware Uploader

The RP2040 / RP2350 Firmware Uploader provides a streamlined way to flash your Raspberry Pi Pico and Pico 2 boards. Unlike the ESP32 which uses Serial, the RP2040/RP2350 series typically uses UF2 (USB Flashing Format) via a virtual disk drive.

This tool leverages the WebUSB API to communicate with the board when it is in BOOTSEL mode. It allows you to select a .uf2 file and write it directly to the flash memory without having to manually drag-and-drop files into a mounted drive.

Features:

Dual-Chip Support: Works with both the original RP2040 and the new high-performance RP2350 (Pico 2).
UF2 Protocol: Optimized for standard UF2 files produced by Arduino, MicroPython, and CircuitPython.
Zero-Install: No drivers or extra software required—just a Chromium-based browser.

Note: The board must be in BOOTSEL mode (hold the button while plugging in) for the browser to detect it.

📖 How to use RP2040 / RP2350 Firmware Uploader

1. Put your board into <strong>BOOTSEL mode</strong> (Hold the BOOTSEL button and connect the USB cable).
2. Upload your firmware <code>.uf2</code> file.
3. Click 'Connect & Flash' and select 'RP2 Boot' from the browser list.
4. The tool will transfer the UF2 blocks and the board will automatically reboot with the new firmware.

❓ Frequently Asked Questions

What is BOOTSEL mode?

It is a special state where the RP2040/RP2350 acts as a USB device for programming. You enter it by holding the BOOTSEL button while connecting the USB cable to your computer.
