Frequently asked questions
Will it work with Raspberry Pi 3 or Pi 4?
The listing names the A+, B+ and 2 B. Those models use the same 40-pin layout as newer boards, but the listing does not confirm Pi 3 or Pi 4 compatibility, so check the mounting and pin fit before using it.
Can I connect 5 V sensors to the GPIO pins?
No. The Raspberry Pi GPIO pins use 3.3 V logic. Use a level shifter for 5 V signals and never apply 5 V to a GPIO pin.
