This board helps connecting two joystick with 18 buttons to a RaspberryPi (B+) configurable with MK-ARCADE_JOY_RPI
With this PCB board you can connect a Rasberry Pi B+ 40pin header to two identical joystic and 18 button. In Retropie program you can use the mk_arcade_joystick_rpi kernel module to configure. https://github.com/recalbox/mk_arcade_joystick_rpi
You can use a normal 40 pin IDE cable to connect the board to the Raspberry Pi.
ATTENTION!! Use the old 40pin cable not the new 80 pin cable, becuse the new has grounding on every line witch makes shortcut.
