Upgrade from 1CH to 8CH
The intended product path is simple: start with a single-channel success, then move to a full multichannel EEG setup on the same DAQ platform.
Why Start with 1CH
1CH is the faster onboarding path:
- simpler bring-up
- fewer connections to debug
- easier signal-quality learning
- fast path to the Engagement Index and focus demo
What Changes When You Move to 8CH
The DAQ workflow stays familiar, but the hardware workflow becomes more demanding:
- more electrode connections
- more site bindings
- more opportunities for channel mismatch or noise
- richer live monitoring and multichannel interpretation
What Stays the Same
- FreeBCI DAQ interface
- browser requirements
- Web Serial connection model
- live monitoring workflow
- EI / focus / session / AI features
What You Should Learn on 1CH First
Before upgrading, be comfortable with:
- safe power-on habits
- how to recognize a stable serial connection
- how to read raw vs. filtered waveforms
- how EI and focus calibration behave in FreeBCI DAQ
Upgrade Checklist
- Finish the 1CH Focus Demo
- Review Spike 8CH ADS1299
- Prepare a full site-binding plan before streaming
- Validate signal quality channel by channel
- Revisit Live Monitoring and Hardware Setup with multichannel expectations
