Introduction
OpenBCI is an open source human brain or bioelectric-computer interface.OpenBCI finished with a built-in high precision special chip (EEG) and brain waves (EMG), heart muscle waves waves (ECG), and other testing and measuring, and one-stop open source (HW, FW, SW), launch team hopes to share and study human bioelectricity mysterious (electrical and electrical body) to learn more about ourselves.
OpenBCI, has eight independent signal acquisition channel, each channel has two side, the root signal one root for reference, and you can configure a number of different channel public or independent) using the reference terminal, this is what electrical module on the market generally does not have (currently on the market other EEG brain electrical module [take common Thinkgear/spirit force of science and technology for] basic provide only one channel, a few to 2 ~ 3), simply a OpenBCI is equivalent to a few common electrical module on the market, and the master for the Arduino UNO,Eeg chips are provided to TI (Texas instruments), a world-renowned semiconductor manufacturer.

Improvement instructions
About the shield
1.Adding 4 positioning holes to facilitate stacking with the motherboard.
2. There are two versions, one is the official original version. The official original version has known power supply problems, which can easily lead to noise during the acquisition process; the other version is the power supply improved version, which uses a high-performance LDO with an output current of 500mA, and the output terminal is stable. The piezoelectric capacitor is changed to 330uF tantalum capacitor, and the wiring is optimized, and the performance is better than the original version.
3. The latest version of the firmware has been refreshed, and the latest official version of the firmware can be continuously updated.
