BillyGate firmware

October 2025

BillyGate is a little bluetooth-low-energy (BLE) dongle that connects chess e-boards (like the Square Off Pro) to chess apps like chess.com and lichess.org. See What is BillyGate?
Download the firmware (low-level software) that powers BillyGate.
Archive firmware:
  • v0.1.4  -  (Sept 2025) previous version
  • flash_nuke.uf2  -  use this (as instructed by BillyGate support) to factory-reset BillyGate 
Follow the BillyGate set-up instructions. This requires one more interaction with BillyGate support. As part of the set-up you need to send us a board ID (that uniquely identifies the Pico2W you bought) and we return you a token that authenticates your firmware for use on that board.
