- Another tall GPIO extension option: Tall 2x20 Female GPIO Header (PTH, 0.1in) (2×20, tall female header) ($4.60)
Standoffs (secure the HAT to the Pi)
- Budget standoff pack: Brass M2.5 Standoffs for Pi HATs - Black Plated - Pack of 2 (M2.5, black plated, pack of 2) ($1.80)
- Alternative standoff pack: M2.5 Standoffs for Pi HATs - Black Plated - Pack of 2 (M2.5, black plated, pack of 2) ($3.40)
Low-profile cooling that fits under many HATs
- For Raspberry Pi 4: XL Raspberry Pi 4 Heatsink - Black (5 mm tall, designed to fit under most HATs) ($3.90)
- For Raspberry Pi 3: Raspberry Pi 3 Heatsink - 6mm (works with HATs) (6 mm heatsink height) ($2.35)
Example Raspberry Pi HAT-based add-ons (if you meant HAT boards)
- Cellular connectivity: EM06-E LTE Cat-6 HAT for Raspberry Pi, Dual Antennas LTE-A, Multi Regions Multi Band, GNSS (LTE Cat-6, dual antennas, GNSS) ($174.10)
- LoRa gateway kit: 8-Channel 915MHz LoRa Gateway Kit with GPS HAT for Raspberry Pi 4 (8-channel, 915 MHz, GPS HAT, made for Pi 4) ($453.41)
Did you mean Raspberry Pi HAT add-on boards (Hardware Attached on Top) or wearable hats?

40 Pin GPIO Male to Female Ribbon Cable - 150mm
A 150mm GPIO ribbon cable for Raspberry Pi with a 2×20 male connector on one end and a 2×20 female connector on the other. Extends the full 40-pin GPIO header for use with HATs, Bonnets, and other accessories at a distance from the board. Works with any 40-pin Raspberry Pi, including the Pi 400 ...
pi-topPROTO
The pi-topPROTO is a HAT-compatible add-on board for prototyping electronics for your pi-top or pi-topCEED. With plenty of space available to build circuits that can interact with your pi-top — as well as a full 40-pin GPIO on top for a desired Raspberry Pi HAT — the pi-topPROTO makes a great add...
2x20pin Extra Tall GPIO Pin Header for Raspberry Pi
This 2×20 pin extra tall male GPIO header stands 12 mm high, providing additional clearance when soldering onto HATs, Bonnets, or custom boards for Raspberry Pi. It's ideal for boards that don't come with headers pre-soldered, or when you need extra height for stacking. Key Features 40-Pin (2×...
Raspberry Pi 400 GPIO Header Adapter, Header Expansion
A GPIO header adapter designed specifically for the Raspberry Pi 400. It connects to the Pi 400's rear GPIO header and provides a standard 40-pin breakout, making it easy to attach HATs, breadboards, and other expansion boards. The header features colour-coded pins for quick identification of po...
Tall 2x20 Female GPIO Header (PTH, 0.1in)
·
This tall 2x20 female header is designed to extend the reach of boards using the standard 2x20 GPIO pin footprint, including Raspberry Pi, Google Coral and NVIDIA Jetson boards.It can also be soldered onto Pi HATs that do not already have headers fitted.
