Access GPIO pins with Inky Phat installed

Support
#1

Hi, I’m working on a project where I’d like a button, a rotary encoder, and an Inky Phat installed on a raspberry pi. I think there are the available GPIO pins on my raspberry pi that the Inky Phat doesn’t use but I’m a bit confused about how to get access to them considering the Inky Phat makes a connection with all the pins (even the ones it doesn’t require)

How can I get access to the pins the inky Phat doesn’t need?

One way to do it is to use Proto Zero with a stacking header. You put it between your Pi and inky.

Another option is to use one of the Hacker boards which will let you access everything.

Thanks, all these products are really useful :)

I should have mentioned that I’m using an rpi4 and an rpi3b+
Do you know which of these options will be best for these boards? From what I can tell the Protozero won’t be right but the Picohat might work

I’ve used this hat sized version of the Proto Zero with Pi 3A+'s and A+'s. Will also work with B series Pi’s.

wow this looks great! Thank you, I appreciate your quick responses

What does the EEPROM do though? I’m not sure if I need the version with that

#7

Get no eeprm version, the eeprom is used by some hats to id them etc. The Sense Hat has one for example. It is optional though. For you or I its not needed and wouldn’t be of any use.
