Schematic Diagram for the Node Device This prototype version uses a TTGO OLED V1 Development Board Based on ESP32 which supports LoRa using the SX1276 LoRa Transceiver. additionally, it also supports WiFi which allows the device to act as a WiFi Access Point for devices like smartphones to communicate with.
List of Parts
List of parts for the prototype Node Device:
| Part | Quantity |
|---|---|
| TTGO OLED V1 Development Board | 1 |
| 10k Ohm Resistors | 2 |
| Tactile push buttons | 2 |
| LED | 1 |
| NEO 6mv2 GPS Module | 1 |
| SPST Switch | 1 |
| AAA Battery | 3 |
| AAA Battery Pack 6v | 1 |
One of the problems of this design is that it uses disposable AAA Batteries and that it requires 5 Volts to operate. A more efficient solution would be using a rechargeable battery with a charging circuit that can be attached to solar panels for charging.
