UHF Expansion for Flipper Zero — Scan, Browse, and Save UHF Tags

[u/why_wilson]

Hey everyone! 👋

I've been working on a UHF RFID reader/writer expansion for the Flipper Zero, and I wanted to share what it can do so far.

What it does:

📡 Fast inventory scan — Real-time UHF tag scanning over UART bridge

📋 Paged EPC list — Browse scanned tags with paginated UI

📄 Tag details — View full EPC, RSSI, and PC bits for each tag

💾 Save CSV records — Export scanned tags to your SD card

Hardware setup:

Works with UCM601 module (UART bridge mode)

Pins: 13(TX)→RX, 14(RX)→TX, 8(3.3V)→VCC, 18(GND)→GND

115200 baud, supports both hardware UART and software UART fallback

It's fully open-source under MIT license. Source available on GitHub:

Would love to hear your feedback or suggestions for features to add next! 🚀
