Without pin header size: 17mm*39mm Just like the bluetooth serial module you have used before it is easy to upgrade to blue 4.0 without changing the PCB and lower computer program! The master-slave integrated module has three functions of transparent transmission remote control and PIO acquisition. It can be switched and set through the AT order set. Like the Bluetooth serial port module you have used before it is easy to change the PCB and the lower computer program. Upgrade to Bluetooth 4.0! Specification Input voltage: 3.3V/5V only needs set of power supply. Built-in level shift function. If 5.0V MCU is used to communicate with the Bluetooth module the 5.0V power port is used for power supply and the RX TX logic level is 5V If a 3.3V MCU is used to communicate with the Bluetooth module the 3.3V power port is used for power supply and the RX TX logic level is 3.3V RX the serial port receiving end of the Bluetooth module is connected to the TXD of the MCU. TX the serial port transmitter of the Bluetooth module is connected to the RXD of the MCU. GND the negative pole of the ground terminal 3.3V power supply terminal 3.3V power supply 5V power supply terminal 5V power supply Packing list: 1*Module
