Arduino UNO Bluetooth 4.0 Shield Keyestudio
The keyestudio Bluetooth 4.0 shield is an integration of sensor shield and HM-10 Bluetooth-4.0, fully compatible with UNO R3. So it is very easy to stack it onto the UNO R3 board.
The shield has extended all the digital and analog pins out into 3PIN, simple to connect the sensor using 3PIN wire.
It also come with a HM-10 Bluetooth-4.0 used for Bluetooth communication. The slide switch is used to control the power supply for Bluetooth.
Onboard is set with jumper cap, default by communicating the Bluetooth module to UNO R3 serial port. If connect two jumpers, need to set the virtual serial port for UNO R3 board, that is D2 to TX, D3 to RX.
Extends 14 digital pins into 3PIN
Extends 6 analog pins into 3PIN
Comes with a reset button
Comes with a slide switch to control the Bluetooth communication
Comes with jumper interface to control the serial communication pin (default built-in serial port, can select the analog serial port, TX to D2, RX to D3.)
Comes with a Bluetooth 4.0 module
