GPIO Assist - Basic

Click to Enlarge



w/ Button Board
(sold separately)

The GPIO Assist boards are designed to simplify the process of wiring a Game Boy Zero while minimizing the amount of space required inside the build. They can also significantly reduce the cost and time it takes to assemble your device. The board sits flush against the back of the Pi Zero W. If you position the board so that the Micro SD slot faces the Contrast port, the wires connecting the button board only need to be about an inch long.

The Basic GPIO Assist board provides easy wiring between a button board and the Pi's GPIO pins, as well as a composite display, PWM audio, a single USB device, an ADS1015 or 1115 for safe shutdown functionality, as well as extra power and ground pads which can be used for things like an audio amplifier. It can also be used with an ILI9341 SPI display. If you wish to use an analog stick in your build, it will need to be wired using a separate microcontroller, such as a Teensy or ProMicro.

For an improved listening experience, please check out some of the audio products, such as the PWM Audio Filter and PAM8403 Audio Amplifier.
