1CH First Power-On
Bring the board up in stages. Do not make the first test a body-connected test.
Before Power-On
Check:
- board matches the intended module release
- no visible solder bridges or reversed parts
- connector orientation looks correct
- battery wiring and polarity are correct
- test area is isolated from unsafe mains-coupled lab setups
First Bring-Up Goal
Your first goal is simple:
- the board powers cleanly
- it does not overheat
- it remains stable long enough to connect to FreeBCI DAQ
At this stage you are validating the board, not yet validating the biological signal path.
Recommended Bring-Up Sequence
- Power the board without electrodes attached
- Observe for obvious faults, instability, or heat
- Connect USB only as required for the isolated DAQ workflow
- Open FreeBCI DAQ and attempt a serial connection
- Confirm that the software sees a stable device
When to Stop
Stop and inspect the setup if you see any of these:
- unstable or repeated disconnects
- signs of overheating
- obvious assembly defects
- behavior inconsistent with the expected module release
Do not proceed to human-connected testing until these issues are resolved.
