Why MasterMind BCI

Built for people who modify their tools

Most EEG vendors ship a black box. We ship the box, the keys to the box, the programmer that opens it, and the source code inside it.

Fully customizable firmware

An STM32H7 runs the show — and you get every line of its C source, STM32CubeProjects, and a compiled firmware file ready to flash. Change filters, streaming protocols, impedance checks, anything.

ST-LINK/V3 in every box

Each BCI-32 ships with a genuine ST-LINK/V3 MINIE debugger. Plug into the onboard SWD header and use STM32CubeProgrammer to flash your builds in seconds — no vendor lock-in, ever.

Firmware file at purchase

The moment your order ships you receive a download link with the matching firmware binary (.hex/.elf), release notes, and regression-test logs — so you can always return to a known-good state.

32 clinical-grade channels

Eight TI ADS1299 front-ends: 24-bit deltasigma ADCs, <1 µV input noise, programmable 1–500 Hz bandwidth, lead-off detection and bias drive on all 32 channels.

3D-printed custom-fit cap

Send us three tape measurements and we print a cap shell with holders for standard electrodes at your 10–20 positions — preview it on a live model before you order.

Everything EEG, one catalog

Wet, dry, gel, paste, caps, cables — the full consumables catalog in one cart, shipping direct from partner warehouses in 2–5 business days.
