Raspberry Pi GPIO

Discussions focus on Raspberry Pi's GPIO pins, IO boards like the Compute Module 4, compatibility with alternatives such as ESP32 and RP2040/Pico, and expansion options for hardware interfacing.

Try the Pi4 Compute Module IO boardhttps://www.raspberrypi.org/products/compute-module-4-io-boa...

What does the pi do? Feels like something that could get replaced with an ESP32 if it needs to be remote or just an ftdi chip or some other usb to gpio if not

Do you already support the Raspberry's GPIOs or do you plan to do so?

yjftsjthsd-h • Jul 6, 2025 • View on HN

I think Raspberry Pis basically give you that via GPIO?

declan_roberts • Jul 4, 2025 • View on HN

Did you not use any of the pi's IO?

Will these ports help Raspberry Pi versions of the same programs?

flak48 • Jun 12, 2024 • View on HN

Do any of the alternatives you've listed expose GPIO pins ?

DrNosferatu • Jan 8, 2025 • View on HN

I guess this could run on the Raspberry Pico - RP2040 / RP2350.

If only they had a version that leaves the gpio pins accessible...

wiredfool • Feb 25, 2015 • View on HN

Would this potentially give a PI way more GPIO pins?
