- PCB size: 37.3mm (L) x 15.5mm (W)
- Input voltage: DC 3.6V~6V
- Anti reverse connection, the board won't work normally if reverse connected
- You can install various types of common Bluetooth module, such as HC05/06/07/BC04 or any other defined pins compatible Bluetooth module
- With clear button, supports module with button pins (such as HC05/06/07 host)
- Pin out 6 pins: VCC / GND / TXD / RXD / STATE / EN
- Set EN to make pins floating or connected high level, module works normally. Turn off thr power when grounding to reduce power consumption (Current <20uA after turing off)
