Beginner Hardware Question - RFID/NFC and e-Paper

Post by sjweathy »

I'm working on a project where I'd like to read a simple string on an RFID tag and then create a qr code based on the string to be displayed on an e-ink/e-paper display using micro/circuit python. I'd also like to make it battery powered. I'm currently using a raspberry pi pico and a generic rc522 and a generic e-ink display.

I'm running into a lot issues with the generic hardware due to lack of documentation or tutorials. Wondering if there's a combination of adafruit hardware that might make this project easier, but am still learning about all of the wings and hats that adafruit makes. Thank you!

The PN532 Breakout is well documented and you can use that with your Pico + CircuitPython.

It would also be even easier to use the PN532 Shield with a Metro M0 to remove any manual wiring.

Thank you so much for the reply. Would it be trivial to add an e-Paper display into the setup you suggested with the PN532 shield and Metro M0? Any other shields/wings/hats or boards that would make this easier?

It's probably worth noting that I don't currently know how to solder. I want to learn, but was hoping to complete this without soldering.

The Adafruit 2.7" Tri-Color eInk Shield would be a good choice to go with a Metro form factor + PN532 shield since they can be stacked. guide

Code: Select all

Metro M0 or M4 (bottom)
PN532 (middle)
2.7" Tri-Color eInk (top)
