Note

  • Schematic: Find the full schematic in the nRFBOX GitHub repository. It details connections for the ESP32, NRF24 Gtmini, OLED, SD card module, and more.
  • PCB Design: PCB files (Gerber, BOM, and pick-and-place) are available in the repository for manufacturing your own boards.

Tip

For extended range, use an NRF24 module with an LNA and connect a compatible antenna to the antenna connector. 📡

Important

Exact pin assignments (e.g., SPI MOSI, MISO, SCK) depend on the firmware configuration. Check the repository’s schematic files or source code for precise mappings.
