Thumbwheel Click is a mikroBUS™ add-on board with a 10-position rotary sprocket connected to a 1-Wire 8-Channel Addressable Switch. The starting position of the switch is marked with a small notch on the PCB above the wheel. Printed numerals from 1 to 10 clearly mark each position. The thumbwheel has a crown with small incisions for better finger traction. The board can use both a 3.3V or a 5V power supply. The One-Wire signal can be sent either through the mikroBUS™ AN or PWM pins. You choose which one by soldering the GP SEL jumper into the right position.
