DAGU AVR DC motor and RC servo controller

Description

Programmable through the Arduino IDE and based on the ATmega8A microcontroller, this compact controller can manage 2 DC motors or 8 small RC servos. The DC motors supply voltage is 9 Vdc with a max current of 2 A (each). It features four control pins, an interface for a Bluetooth module (not included) that allows using the controller with cell phones and PCs, a jumper to select the power supply type, an external PWM control signal, a reset button, and an on/off switch. Pins D0 and D1 are the serial port RX and TX pins, D2 and D3 are the external interrupt pins, D9, D10, and D11 are the PWM pins, D10, D11, D12, and D13 connect to the ISP socket, D13 is a default output, and A4 and A5 are the SDA and SCL pins for the I2C interface.
