1pcs Five Direction Navigation Button Module for MCU AVR Game 5D Rocker Joystick Independent Keyboard for Arduino Joystick

Pin and Wiring Instructions for Key Module

I. Pin Functions

● COM: Common terminal, needs to be connected to VCC or GND of the MCU development board

● UP: "Up" direction key, connect to MCU IO pin

● DWN: "Down" direction key, connect to MCU IO pin

● LFT: "Left" direction key, connect to MCU IO pin

● RHT: "Right" direction key, connect to MCU IO pin

● MID: "Middle" direction key, connect to MCU IO pin

● SET: "SET" key, connect to MCU IO pin

● RST: "RST" key, connect to MCU IO pin

II. Wiring Instructions

The development board and the key module are connected correspondingly through pins. Taking GPIO pins as an example:

  Development Board VCC → Key Module COM

  Development Board GND → Key Module COM

  Development Board GPIO_0 → Key Module UP

  Development Board GPIO_1 → Key Module DWN

  Development Board GPIO_2 → Key Module LFT

  Development Board GPIO_3 → Key Module RHT

  Development Board GPIO_4 → Key Module MID

  Development Board GPIO_5 → Key Module SET

  Development Board GPIO_6 → Key Module RST

(Note: The actual wiring can be adjusted according to the pin resources of the development board, as long as the functions correspond )
