# Analog Rotation Brick(EF04085) ## Introduction Octopus analog rotation brick is a 10K potentiometer module. Rotating the knob to change its resistance can realize voltage division, and can provide analog signals to the analog input IO ports of microcontroller. This module has a 3wire antireverse connector, which makes it easy to connect a GVS cable. ## Products Link [ELECFREAKS Octopus Analog Rotation Brick-Blue](https://shop.elecfreaks.com/products/elecfreaks-octopus-analog-rotation-brick-blue?_pos=1&_sid=d76e1f7cf&_ss=r) ## Characteristics Adopting 3 pins cable with antiplug function.
