The OpenBCI 32-bit board uses the ADS1299, an
IC developed by
Texas Instruments for biopotential measurements. The OpenBCI uses a
microcontroller for on-board processing — the 8bit version (now deprecated) uses an
Arduino-compatible ATmega328P IC, while the 32bit board uses a
PIC microcontroller — and can write the EEG data to an SD card, or transmit it to software on a computer over a
bluetooth link. In 2015, OpenBCI announced the Ganglion board with a 2nd
Kickstarter campaign. It has 4 input channels for measuring EEG, EMG, and EKG, and is also Bluetooth enabled. Initially it was offered on Kickstarter at $99, before later being listed at $249.99, and subsequently increasing in price to $499.00. == Software ==
