On the motherboard, three-dimensional acceleration sensor and TF card slot have been welded. The firmware version is the latest version and can be upgraded later\u003cbr\u003e* WiFi Shield for OpenBCI has improved the known bug of the original version (the bug will cause noise during the acquisition process). The latest version of the firmware has been flashed, and the firmware can be continuously upgraded\u003cbr\u003e* Power board compatible with lithium battery for OpenBCI: Onboard 2000mAH lithium battery ensures long endurance time. Support USB charging via a type C interface, and charging current is set to 250mAH\u003cbr\u003e* Since the USB type C charging interface is not isolated, do not collect EEG signals during charging\u003cbr\u003e* Support the latest version of the host computer for OpenBCI GUI\u003cbr\u003e* Use Wifi technology instead of Bluetooth module, enabling higher sampling rate\u003cbr\u003e\u003cbr\u003e\u003cb\u003eVersion With Shell:\u003c\/b\u003e\u003cbr\u003e* Three status indicators on its front side\u003cbr\u003e* Its bottom with two indicators of charging management - Yellow light is on means that it is charging; and red light is on means it is charged\u003cbr\u003e* With built-in battery and USB type-c charging port reserved\u003cbr\u003e* The front end of the shell has a hole, and the DuPont head extends out for easy insertion of lead electrodes.\u003cbr\u003e* The right opening reserves a position for toggle switch\u003cbr\u003e* The shell is made by 3D printing process.
