BC04-B Master Slave Selectable Bluetooth Module Shield 5V/3.3V with Switch
BC04-B Master Slave Selectable Bluetooth Module Shield
Overview
This is redesigned arduino bluetooth shield based on our BC04-A module, arduino stackable, and use use arduino pin 3 and 4 as software serial port for communication.
Features
Master/Slave selectable, based on BC04-B module
LED indicator the bluetooth status, fast flashing means not paired yet, constant high status is paired. This is also connect to the arduino digital pin2
Reset Button can clear the pairing status.
A lot of standard 2.54 pins available for use.
Specifications
Settings :
UART D0/D1 or D3/D4: Use either software serial port of arduino digital pin 3 (RX) and 4 (TX), or original UART port of digital pin 1(TX) and 0 (RX)
Output/Arduino: Connect the uart of the bluetooth module to either external serial pins or to the arduino board.
5V/3V3 Switch: Set the UART logic power level, either 5V or 3V3, keep it at 5V to give the UART pins better power level protection.
