I'm working on a project using the google AIY Voice Kit V2 as a base. I'm planning on adding a keypad which requires 12 GPIOs. Does anyone know of a way to add more GPIOs to the Pi Zero W with AIY Voice Kit?

  • why does a keypad require 12 data lines? – jsotola May 18 '19 at 16:39

You can use a break-out board like the Black HAT Hacker or Pico HAT Hacker.

Alternatively, connect another Pi Zero as a USB gadget and use the GPIO expander.
