Heltec ESP32-S3 MCU + SX1262 LoRa 868MHz Wireless Stick(V3) Development Board With 0.49inch OLED Display

Wireless Stick is a development board for Wi-Fi, Bluetooth and LoRa. Its functions are basically the same as “WiFi Lora 32”, except that the screen is reduced to 0.49 inch and a shielding shell is added.

The Wireless Stick is composed up of an MCU (ESP32-S3FN8) and Semtech LoRa Transceivers (SX1262), perfectly support Arduino. Users can easily carry out secondary development and application.
