  1. Disconnect Eurorack power.
  2. Connect the XIAO RP2350 over USB.
  3. Use the USB BOOTSEL button below, or enter BOOTSEL manually.

About MOD2 Firmware Flasher

This site is a firmware catalog and browser-based flashing tool for the HAGIWO MOD2 platform built around the Seeed XIAO RP2350.

Each card describes one firmware, its author, tags, hardware notes, control mapping, README, source file, and UF2 download.

Flashing Flow

  1. Disconnect Eurorack power before connecting USB.
  2. Connect the XIAO RP2350 over USB.
  3. Use Enter BOOTSEL over USB, or enter BOOTSEL manually.
  4. Use Flash selected firmware to write and verify the UF2 via Picoboot.

Browser flashing has been validated on MOD2 / XIAO RP2350 with both small and large UF2 files. Manual UF2 download is kept as a fallback.

Browser Requirements

WebUSB and WebSerial require Chrome, Edge, or another Chromium-based browser, served from HTTPS or localhost.
