Frequently Asked Questions

What Raspberry Pi models are compatible with this GPIO expansion board?

This GPIO expansion board is primarily designed for and compatible with Raspberry Pi 3, 3B+, and 4B models. While electrically compatible with older 40-pin Pis like the Pi 2 and Model B+, its physical mounting and dimensions are optimized for the later generations, ensuring a secure fit.

How does the 1-to-3 GPIO expansion board function?

The board electrically duplicates the Raspberry Pi's single 40-pin GPIO header into three identical 40-pin headers. Each expanded header provides full access to all GPIO pins, power rails (3.3V, 5V), and ground, allowing multiple HATs or modules to share the same GPIO lines without conflict, assuming proper addressing.

Is external power required for the expansion board and connected peripherals?

No, the expansion board itself does not require external power. It draws power directly from the Raspberry Pi's 5V and 3.3V rails. However, if the combined current draw of all connected peripherals exceeds the Raspberry Pi's power supply capabilities, an upgraded PSU for the Pi may be necessary.
