Data Sheet
3.3 Mechanical Dimensions
The following diagram may be used to develop PCB carrying boards or enclosures used to fit the
controller into custom designs. The mounting holes may be used with 2-56 machine screws and nuts
3.4 Connectivity Overview
3.5 Indicator LEDs
D2 (green) will light briefly when serial communication is received, and will also blink once on power-up.
D3 (red) will light when the motor voltage is less than ~5.6V, the current exceeds 6A, or the temperature
on the PCB exceeds 175°C. The red LED will turn off when the fault condition disappears, but a FAULT
bit will remain set in the STATUS register until that register is read.
