Printers and parts I use
The printers my projects support and the parts that work with them. Each card names the projects it works with. Hardware test status for each reader chip is in the reader comparison.
3D printers
The Flashforge printers my projects support, and the Snapmaker U1, whose spool tags my readers can read.
ESP32 boards
The brains of the Wi-Fi reader and the USB bridge.
NFC reader modules
Start with a PN532. Get a PN5180 if you want OpenPrintTag (ISO 15693).
NFC tags
For spools that don't come with a tag.
Networking
Wired Ethernet for the Creator 5 Pro.
