modeScan nearby tags, browse a paged EPC list, inspect tag details and export captured records to CSV on the Flipper SD card.Windows PCFull reader/writer modeConnect by USB-C for inventory, memory-bank read/write, lock and kill operations through the dedicated Windows software.AndroidMTools OTG modeConnect the expansion to a supported Android device over USB OTG and operate it with the MTools app.Open-source Flipper applicationSee the tags, not just a blinking LEDThe companion app presents the complete inventory workflow on the Flipper Zero screen—from live tag count to individual EPC details.Inventory Scan01Paged Tag List02Tag Details03Action Menu04Field inventory essentialsA purpose-built interface keeps the most useful UHF information available without carrying a laptop.⌁Fast inventory scanStart and stop scanning from the Flipper Zero and watch the detected tag count update in real time.EPCBrowse captured tagsMove through a paged EPC list, select an entry and inspect its full EPC instead of relying on a truncated preview.dBUseful tag diagnosticsView EPC, RSSI and PC (Protocol Control) bits for each captured tag directly on the Flipper display.CSVSave records to SDExport inventory records as a CSV file for later review, documentation or processing on another device.Hardware UART · 115200 baudDirect GPIO connectionThe 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.Flipper Zero pinUHF Expansion13 (TX)RX14 (RX)TX8 (3.3V)VCC18 (GND)GNDBuild and launch the Flipper appThe application source is public and can be built with the official Flipper Zero build tool.CloneDownload the open-source application from the MTools Tec GitHub repository.BuildRun ufbt build in the project directory to create the application package.LaunchUse ufbt launch, or copy the FAP to SD Card/apps/GPIO and open it from Apps → GPIO.git clone https://github.com/mtoolstec/fz-uhf-expansion.gitcd fz-uhf-expansionufbt buildufbt launch UHF Reader Windows ProgramUse the Windows program for real-time UHF inventory and supported EPC Gen2 / ISO 18000-6C read, write, lock and kill operations.
