The KEYBOT Coding Robot Control Board is particularly designed for car robot control.
This control board has integrated the UNO R3 control board and a motor drive board into one circuit board, which can directly drive two DC motors.
For the convenience of car design, this control board comes with a Bluetooth interface (fully compatible with HC-06 Bluetooth module), 2 servo interfaces and a passive buzzer. For easy car control, this control board also comes with 2 slide switches and a reset button. The large slide switch is used for an external power supply control. While the small switch is used for the serial port communication of Bluetooth module.
For simple connection, it extends all the digital and analog ports out as RJ11 sockets. It also comes with a power interface. The RJ11 socket integrates the digital and analog ports together, so you just need a cable to connect it with sensor modules, pretty simple and convenient.
