3. Getting Started
TReX input/output connection points
Getting started with your TReX can be as simple as connecting power, your motors, and your RC or analog control
signals (see
Section 3.a and Section 3.b ). Configure your jumpers for RC or analog mode (see Section 3.c ) and
you’re good to go. While it’s running, the TReX will communicate with you via its LEDs (see Section 3.d ). Once
you have all your connections in place, we recommend your first step be to calibrate your TReX for your particular
RC or analog controller (see
Section 3.e ).
3.a. Motor and Power Connections
The TReX receives its power through the VIN/GND connector terminals. VIN should be between 6 and 16 V and
your power source must be able to supply the current your motors will be drawing. The TReX can supply peaks
of 30 A and up to a continuous 13 A to each of its two bidirectional motors. Performance will depend the on
actual system and its ability to dissipate heat. The TReX’s bottom motor driver board is designed to help heat flow
away from the VNH2SP30 motor driver chips, but addition of a heat sink and good air flow will further improve
performance. The TReX can supply up to 15 A (continuous) to the auxiliary motor.
There are several different ways to connect motors to your TReX:
