Four new boards, all authored with KiCad 10: - hmi/communication/XIAO_COM: XIAO-based com module (README, HARDWARE.md, plots, gerbers, STEP/STL) - hmi/submodule/sensor/EMG_DAQ_ADS1292: ADS1292 EMG front-end with an electrodeFilter sub-sheet. Its README and description.yaml were copied from the ADS1293 module and still named that chip -- corrected here. - hmi/submodule/v2/emgvib: combined EMG + vibration submodule - tool/flexBracelet: flex bracelet with JLCPCB production files Still missing and left for a follow-up: description.yaml for XIAO_COM, and README + description.yaml for emgvib and flexBracelet.
