Maker Hat Base extends out all the GPIOs of the Raspberry Pi 400 in a quick and simple way - be it using your favorite HAT or building your own simple circuit with jumper wires on the mini breadboard.

Since a ribbon cable is used for the connection, the Maker Hat Base is compatible with the Raspberry Pi 3 and Pi 4 too. This is especially useful when the Raspberry Pi is enclosed in a case and you want to extend its GPIOs out for HAT.

Each GPIO pin is clearly labelled and its status LED is definitely helpful during testing and troubleshooting. The onboard buzzer and push buttons will get you start coding in no time without the need of building your own circuit. Wanna connect to some external sensors/ modules? Worry not! The onboard Grove ports (GPIO, UART & I2C) is there for you.

  • Specially designed for Raspberry Pi 400.
  • Compatible with Raspberry Pi 3 & 4.
