Overview

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.
