dB · Useful diagnostics

View EPC, RSSI and PC (Protocol Control) bits for each captured tag directly on the Flipper display.

CSV · Save records to SD

Export inventory records as a CSV file for later review, documentation or processing on another device.

HARDWARE UART · 115200 BAUD

Direct GPIO connection

The open-source application uses the Flipper Zero hardware UART on pins 13 and 14. The module is powered from the 3.3V and GND pins.

Important: Disconnect power before changing wiring. Confirm every pin before powering the module; reversed power or crossed connections may damage the hardware.
