WiFi LoRa 32 is a classic IoT dev-board, it has been loved by developers and makers. The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions.
It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.

Different between V2 and V3
1. MCU is different. V2 uses ESP32-D0WDQ6, and V3 uses ESP32-S3FN8. This results in different GPIO pin definitions.
2. LoRa chips are different. V2 uses SX1276/8, and V3 uses SX1262.
3. The USB interface is different. V2 uses Micro USB, and V3 uses USB Type-C.
