Ganglion Board (4-channels)
Our 4 channel bioamplifier. The Ganglion is a favorite low-cost choice for collecting scientifically-validated physiological data.
The Ganglion Board is a scientifically-validated research tool
- This kit does not include electrodes. It is compatible with our EEG Headband Kit, Gold Cup Electrodes, EMG/ECG Snap Electrode Cables, and Header pin to touch proof electrode adapter.

The OpenBCI Ganglion is a high-quality, affordable bio-sensing device, compatible with OpenBCI's free open-source software. On the input side, there are 4 high-impedance differential inputs, a driven ground (DRL), a positive voltage supply (Vdd), and a negative voltage supply (Vss). The inputs can be used as individual differential inputs for measuring EMG or ECG, or they can be individually connected to a reference electrode for measuring EEG. Data is sampled at 200Hz on each of the 4 channels.
We are using a Simblee for our on-board microcontroller and wireless connection. Simblee is RF Digital’s next generation Arduino-compatible radio module. The new Simblee provides user programmable flash, 29 GPIO pins, and the ability to update software over the air (OTA). Every Ganglion will be pre-programmed with versatile firmware so you can get started sensing your body right out of the box. We will also break-out up to 16 of the GPIOs for you to hack with.
