The ElecFreaks Octopus Analog Rotation Brick-Blue is a 10K potentiometer module.
Rotating the knob to change its resistance can realize voltage division while providing analog signals to the analog input IO ports of the micro-controller. This module has a 3-wire anti-reverse connector, which makes it easy to connect a GVS cable.
