JY-MCU Bluetooth Serial Port Module (Master)

The Hobby Components wireless Bluetooth module is intended to be used in conjunction with our Bluetooth slave module (HCARDU0004). When the module is correctly connected to a 3.6 to 6V supply and a slave is within range, the master module will automatically pair with the slave module. This means a serial to serial connection over a wireless Bluetooth link can be made without requiring any software interaction.

Please note that if you require a module for connection to other Bluetooth devices such are a PC, smart phone, etc., please purchase our slave module instead (HCARDU00004).


Default Baud rate: 9600

Although this module requires no software interaction, an example Arduino program that is useful for evaluating the module can be found on our support forum here.
