Introduction
BPI-BT BLE 4.2 control module is a kind of maker product of wireless bluetooth intelligent control. It supports bluetooth BLE4.2 protocol. Through the connection of smart phone BLE bluetooth, it can control LED lights, N20 motor, micro-steering machine, relay, electromagnet and other low-voltage devices, which facilitates the makers to realize their creativity.
BPI-BT BLE 4.2 control module is a wireless Bluetooth product, supporting Bluetooth BLE4.2 protocol, via smartphones BLE Bluetooth connection, with the aid of the ovorobot graphical development platform and the APP can be external control LED lights, N20 motor, micro servo, relay, electromagnet low voltage devices, such as convenient and maker realize their ideas. The interface of pass-through serial port is reserved. Users who need further DIY can upload the data of mobile phone to their control unit.

- name is also marked on the PCB board
| Main interface description of BPI-BT BLE 4.2 control module | |||
| Name | Description | ||
| D1 | The maximum current is 200mA, and the ground (GND) is connected after conduction. Can connect low current motor. IO port 1 control. | ||
| D2 | The maximum current is 200mA, and the ground (GND) is connected after conduction. Can connect low current motor. IO port 2 control. | ||
| D4 | Output 3.3v high and low level, weak current, can connect LED lamp. IO port 4 control. | ||
| 1，2，3，4, | PWM output, control pulse port 1,2,3,4 through software. The duty ratio can be set, which can be used to control the steering gear Angle, to adjust the motor speed, to make the breathing lamp (gradually increasing and decreasing), or to be used as the driving square wave output of the stepping motor module. | ||
| M1 | Motor drive port, double up and down. Control direction by software IO port 3 and speed by pulse port 3 | ||
| M2 | Motor drive port, double up and down. Control direction by software IO port 4 and speed by pulse port 4 | ||
| + | Power positive terminal, use DuPont port. Maximum current 2A. | ||
| - | Negative power supply. Use the DuPont port. | ||
| T,R,G, | The serial port sends, receives, GND interface and does not weld connectors. When the user needs, he/she can weld lines or connect them with probes. The data of smart phone can be output to the serial port through Bluetooth transmission mode for external modules to use. | ||
