Choose Your Module

Start with the module that matches your goal, then move up to the full multichannel workflow on the same DAQ platform.

Module	Best For	What You Get	Typical Outcome
FreeBCI Spike 1CH LH001	Beginners, makers, classroom demos, fast iteration	Single-channel biopotential acquisition	First signal, first waveform, focus / engagement demo
FreeBCI Spike 8CH ADS1299	EEG builders, researchers, multichannel prototyping	Eight-channel EEG acquisition	Multichannel waveforms, site-aware setup, richer analysis

Start with 1CH if...

• You want the fastest path to a working FreeBCI system
• You want to demo Engagement Index and binary focus classification
• You are learning electrode basics, signal quality, and DAQ workflow
• You want a lower-complexity bring-up path before moving to multichannel EEG

Go to: Spike 1CH LH001

Choose 8CH if...

• You already understand the basics and want full EEG channel mapping
• You need multiple electrode sites connected at the same time
• You want a more complete spatial setup for monitoring and analysis
• Your goal is system prototyping, experimentation, or multichannel demos

Go to: Spike 8CH ADS1299

Shared Software Platform

Both modules are supported by FreeBCI DAQ.

• Same browser-based acquisition workflow
• Same Web Serial connection model
• Same live monitoring, EI, focus, and AI analysis surfaces
• Different hardware complexity and setup depth
