Motor ECU

<Picture and link to Gitlab>

Hardware Design

The DC motor, electronic speed control (ESC), and servo motor were included with the Traxxas Slash.
...

For speed sensing we purchased a Traxxas RPM sensor as it mounted nicely in the gear box. The RPM sensor works by mounting a magnet to the spur gear and a hall effect sensor fixed to the gear box. To get the revolutions per second we used Timer2 as an input capture.
