Cytron Maker HAT Base GPIO Expansion Board for Raspberry Pi 400
GPIO expansion board for Raspberry Pi 400. Extends all pins, has LEDs, buzzer, buttons, Grove ports, and 3.3V regulator.
The Cytron Maker HAT Base is an all-in-one I/O expansion board engineered specifically for Raspberry Pi 400. It extends every GPIO pin in a clear and accessible layout, allowing you to use your existing HATs or prototype your own circuits with ease.
The board features clearly labelled GPIO breakouts for quick jumper wire connections and includes status LEDs for each GPIO, giving you real-time visual feedback. On-board programmable elements include a buzzer and four push buttons, perfect for interactive projects without extra wiring.
Connect external modules via three Grove ports (GPIO, UART, I2C) to easily interface with sensors and actuators. The integrated 3.3V regulator supplies extra current up to 800mA for power-hungry add-ons.
