WIP - dual pcb arm band for multi channel semg acquisition
Clamshell design, 8 channels, modular design with DB and MB
Status:
Current plan is to finish design of DB, get boards manufactured, and test with nrf5340 devboard. After testing confirms functionality, design a pcb to stack with the DB to move SoC functionality, IMU, and power to the wrist. HW:
- DB : schematic complete, layout underway
- MB : schematic v1 complete, in need of revision
DB PCB Progress (9-10-26) - see docs/db/daughterboard-adr.md for more details.
- no ground pour currently - need different planes for analog and digital
- need to confirm power rail is within spec (max current is 1.2A)
- Need to better organize silkscreen lettering
Barebones layout gets finalized.
- devboard: flashing + building works, no progress on actual functionality
- final PCB: n/a
