- 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)
