Arduino joysticks expansion board ElecFreaks Joystick shield V1.0
Description:
Arduino JoyStick Shield with a cross PS2 joystick with buttons, as well as four radio buttons, 2 small buttons. Provides for the Arduino and the key input extension joystick. On-board switch can switch between 3.3V and 5V, 3.3V can use this module for other microcontroller platforms, such as the STM32.
All signals are transferred through standard pin 2.54 leads to facilitate the transfer to other microcontroller platforms.
