The T’REX controller from DAGU is an Arduino compatible robot controller designed to power and control servos and brushed motors. Supplied samplecode allows the controller to connect to a radio control receiver , external controller via I²C or optional bluetooth interface. A sample app allows the controller to be controlled by an Android phone or tablet.
The A Tmega328P controller comes with the Arduino bootloader and customer software can be uploaded viathe built in USB interface, ISP or FTDI sockets.
The Dual H bridges are rated for stall currents of 40A per motor and average currents of 18A per motor. Factory calibrated hall-effectsensors measure current draw of each motor . Each motor has independent variable electronic braking. Self-resetting PTC fuses prevent damage from stalled motors.
The built in switch mode power supply allows the controller to work over a wide range of voltages from 6V – 30V and delivers 3A of current at 6V for driving servos. The 5V LDO regulator can deliver in excess of2A if required for poweringan external controller . A built in 3-axis accelerometer provides robots with angle, acceleration and impact data.
