## Description

N20 motors are very popular for small-scale robots applications, because they're super compact, powerful, and durable. The entire motor fits within the 12mm x 10mm profile of the gearbox, which has a gear ratio of 31.5:1 and 10mm long 3mm diameter D-shaft. This pair also includes magnetic encoders with 14-pole magnets, enabling a resolution of 882 counts per revolution of the output shaft. They are rated for up to 12V, at which they can achieve a speed of 1000RPM at 0.06A. Those specs are approximately halved when using at 6V, such as with the XRP. Speaking of which, the pre-soldered 100mm cable has a 6-pin JST-SH connector that plugs directly into the XRP Controller for each integration for projects with the XRP.
