TReX Jr input/output connection points

Getting started with your TReX Jr 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 Jr 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 Jr for your particular RC or analog controller (see Section 3.e).
