Pico HAT Hacker

The Pico HAT Hacker is an ultra-thin breakout board that gives you full access to all 40 GPIO pins while still allowing you to stack HATs or pHATs on top. At just 0.8mm thick, it solders directly onto your Pi's GPIO pins with minimal added height.

Dual-sided labelling shows BCM pin numbers on one side and functional labels (I2C, UART, SPI, PWM, I2S) on the other, so you can orient it based on your preferred reference.
