Description:

Integrates sensor expansion board with HM - 10 Bluetooth 4.0.

It is fully compatible with R3 control board, which can work only through stacking the expansion board on the R3 control board, easy and convenient.

It extends all digital ports and analog ports of 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.

There is a jumper cap set on the board, and the default jumper wire achieves the direct communications between bluetooth module and R3 control board serial port.

If the jumper cap connect another two jumper wires, achieving a serial port communication needs the R3 control board to set up the virtual serial port, which needs that the digital port 2 is set to RX, and digital port 3 is set to the TX.
