Integrates sensor expansion board with HM - 10 Bluetooth 4.0.
It is fully compatible with keyestudio UNO R3 control board, which can work only through stacking the expansion board on the UNO R3 control board, easy and convenient.
It extends all digital ports and analog ports of UNO R3 control board in the form of steering gear sequence.
A sensor only needs a universal 3P sensor cable, which is very simple and fast.
Expansion board with HM - 10 Bluetooth 4.0 can be used for the bluetooth communication, and toggle switch control the power supply for Bluetooth.
