Hi @chunksin, is this a good BOM to sticky somehow for those following your progress? Are you still looking for a copy of ID7?Raspberry Pi 3A or 3B or 3B+ or 4B and microSD card, 8GB is fine
USB to serial adaptor - I use the TrendNet TU-S9 but anything using the Prolific PL230x chipset is fine
Female to Female 9 pin serial cable
ACR122U card reader
Mifare 4k NFC cards - any generic ones should work fine
If you want to power the Pi with 5v from the DC Out connector on the Ringedge you can make up a Molex to USB connector with these:
14 Way Molex Mini-fit Jr. 5557 Series Female White
Model: FF55-39012145-H
Molex, Mini-Fit 5556, Female, Contact,16awg
Model: FA51-39000077-T
