## Description

This 139:1 ratio gear motor runs at a no-load speed of 43RPM when 12VDC is applied. Mounted to the back of the [Modern Robotics/MATRIX 12VDC Motor](https://core-electronics.com.au/modern-roboticsmatrix-12vdc-motor.html) driving the gearbox is a quadrature encoder able to run on both 3.3V and 5V. Its bullet connectors are a reliable connection style that allows you to easily reverse polarity to the motor and pass its wires through 14mm holes in goBILDA® channel, even when grommets are installed.
