The Pico HAT Hacker gives you full access to all 40 GPIO pins on your Raspberry Pi, broken out at the top of the board. Its ultra-thin 0.8 mm PCB can be soldered directly onto the Pi's header pins while still leaving enough pin height to stack a HAT or pHAT on top.

Both sides of the board feature pin labels — BCM pin numbering on one side, and descriptive labels (I2C, UART, SPI, PWM, I2S) on the other. Solder it either way up depending on which labels you prefer.

Key Features

• Full 40-Pin Breakout – Access all GPIO pins while a HAT is stacked above
• Ultra-Thin PCB – 0.8 mm thick; fits between the Pi and a HAT/pHAT
• Dual-Sided Labels – BCM numbering on one side, descriptive pin names on the other
• M2.5 Mounting Holes – Standard Raspberry Pi mounting pattern

Specifications

• Dimensions – 65 × 19 × 0.8 mm
