Breadboard‐Setup
No custom PCB? No problem! You can build the nRFBOX on a breadboard with off-the-shelf components. Here’s how to get started. 🛠️
- ESP32 module
- NRF24 module (LNA version recommended for better range)
- 0.96-inch OLED display (128x64 resolution)
- TP4056 battery charging module
- SD card module
- Antenna connector (optional for extended range)
- Push buttons (for navigation)
- NeoPixel LED (optional)
- Breadboard, jumper wires, and a lithium battery
- Connect the ESP32-U: Wire the ESP32 to a breadboard with proper 3.3V power and ground connections.
- Add the NRF24: Hook up the NRF24 module to the ESP32 using SPI pins (see the schematic in the repository).
- Wire the OLED Display: Connect the 0.96-inch OLED to the ESP32’s I2C pins for real-time data display.
- Add the SD Card Module: Wire the SD card module to the ESP32 for firmware updates and data storage.
- Add Push Buttons: Connect buttons for menu navigation (check the pinout in the schematic).
- Optional Components: Add the NeoPixel, antenna connector, and battery charging circuit (TP4056) as needed.
