Cyton + Daisy Overview
The Cyton OpenBCI Board is an Arduino-compatible, 8-channel neural interface with a 32-bit processor. At its core, the Cyton OpenBCI Board implements the PIC32MX250F128B microcontroller, giving it lots of local memory and fast processing speeds. The board comes pre-flashed with the chipKIT™ bootloader, and the latest OpenBCI firmware.
The OpenBCI Cyton Board and OpenBCI Daisy Module (which plugs into the OpenBCI Cyton Board) can be used to sample up to 16 channels of brain activity (EEG), muscle activity (EMG), and heart activity (ECG). The system communicates wirelessly to a computer via the OpenBCI USB dongle using RFDuino radio modules. It can also communicate wirelessly to any mobile device or tablet compatible with Bluetooth Low Energy (BLE). The Cyton Daisy Board samples data at 125 Hz on each of its 16 channels. However, if you select the “save data to microSD card” option in the OpenBCI GUI, you can take advantage of the 250 Hz sampling rate.
The board and dongle come pre-loaded with the latest firmware, making OpenBCI accessible to researchers and developers with little to no hardware experience. OpenBCI boards have a growing list of data output formats, making them compatible with an expanding collection of existing biofeedback applications and tools.
