Product Description
BrainBit Flex4 – Wireless 4-Channel EEG Cap for Research & Development
The BrainBit Flex4 is a compact, portable EEG system with four freely placeable electrodes. The electrodes (dry or wet) can be positioned on the included EEG textile cap according to the standardized 10–20 system. Suitable for research, development, neuromarketing, and cognitive/emotional state analysis.
Wireless and developer-friendly: Data transfer via Bluetooth Low Energy (BLE / 4.0 LE), up to 12 hours of battery runtime, and a free SDK (Windows, macOS, Linux, Android, iOS) for custom applications.
Note: The BrainBit Flex4 is not a medical device and is not intended for diagnosis, treatment, or disease prevention. A manufacturer’s conformity declaration per the relevant EU directives (e.g. EMC, RoHS) is available.

Flex – Agile 4-Channel Setup
- Free electrode placements (10–20)
- 250 Hz, BLE, up to 12 h
- Go to Flex product page
Flex8 – For advanced protocols
- More channels (8) for dense montages
- 250 Hz, BLE, same platforms
- Go to Flex8 product page
Conclusion: Flex is suitable for versatile research applications and entry into EEG-based analyses. For more channels and more complex protocols, Flex8 provides an extended feature set.
Buying Guide – suitability by use case
Summary: Flex aligns with agile 10–20 setups using 4 channels and short preparation without gel; Flex8 matches scenarios requiring more channels and complex EEG protocols.
Recommended for Flex4 (4-Ch)
- Requirement: free electrode placement in the 10–20 system
- Preference: short setup without gel
- Mobile operation (BLE; runtime up to 12 h)
- Operation with standard 250 Hz sampling
Recommended for Flex8 (8-Ch)
- Need for more channels to support dense montages and protocols
- Planned complex studies or ML pipelines
- Team/lab setups with parallel measurement points
- Identical SDK/OS base as Flex desired
