Pimoroni pHAT Stack for Raspberry Pi

Product ID: 3742


We're doffing our Mini Black HAT Hack3r for the evening because it's showtime for Pimoroni's pHAT Stack! This expansive breakout PCB offers 6 sets of 2x20 pin headers - one for connecting to your Pi and the other 5 for a plethora of HATs, pHATs or bonnets.

The combinations are endless... It's perfect for your projects, displaying temperatures, times, etc. and becomes really useful when combined with other boards like the OLED Bonnet or Inky pHAT plus maybe a Enviro pHAT to display the sensor values.

Before you cobble your set-up, we recommend checking that your boards are all compatible with each other. Since the Raspberry Pi has a limited number of GPIO pins, there's a strong chance your pins may clash. Take a looksie at Pinout's cool experimental Raspberry Pi pinout configurator and of course check the specification sheets, pinouts or datasheets for all your fancy add-ons.
