- ESP32 development board with 8 MB Flash
- a SemTech SX1276 for 915MHz LoRaWAN communication (SX1278 for 433MHz)
- a SSD1306 0.96-inch 128x64 OLED display connected via I2C.
- Heltec_ESP32 Library for LoRa and OLED.
- I like to use libraries radiolib and SSD1306 directly.
- I made this demo
- GPIO16 should be pulled up internally to turn on OLED~
