DAGU T’REX Driver board

Description

Based on the ATmega328P, the DAGU T’REX driver board is a board capable of controlling the speed and direction of rotation of two DC motors with a continuous current of 9A (40A peak) and 4 RC servos at 6V. Equipped with a 3-axis accelerometer and resettable fuses (PTC), it can be controlled in I2C, RC mode, and via the DAGU Bluetooth module (not included) which allows managing the driver with a smartphone. It also features a 5V 2A power output that can power a Raspberry Pi or other 32-bit controllers. The ATmega328P comes with a bootloader to upload your own sketch directly via USB, ISP, or FTDI interface. Dimensions (mm): 110x60x23. Particularly suitable for use with the T’REX TANK (not included).
