Based on the ATmega328P, the DAGU's T'REX driver board is a board capable of controlling the speed and direction of rotation of two DC motors with a continuous 9 A current (40 A peak) and 4 RC servos. Equipped with a 3-axis accelerometer and self-resetting fuses (PTC), it can be controlled in I2C, RC mode and via the DAGU Bluetooth module (not included) which allows the driver to be managed with a smartphone. It also has a 5V 2A power supply output that allows you to power Raspberry Pi or other 32-bit controllers. The ATmega328P is supplied with a bootloader to load your Sketch directly via USB, ISP or FTDI interface. Dimensions (mm): 110x60x23.
