Octopus Electronic Bricks! You can use them build electronics projects just as easy as piling bricks! By using Octopus electronic bricks, you may connect Arduino or compatible boards easily with various digital, analog and I2C/Uart interfaces. These breadboard-less firm connections includes an extensive collection of modules like potentiometers, sensors, relays, servos, and even buttons.  Just plug and play!

The Octopus analog rotation brick is a 10K potentiometer module! Rotating the knob changes the resistance, which  provides an analog signal to the analog input IO ports of a micro-controller. This module has a 3-wire anti-reverse connector, which makes it easy to connect a GVS cable.


  • Integrate a 3-wire anti-reverse connector.
  • Rotate the knob to adjust resistance without using a screw driver.
  • Compact structure.
