ESP32S3 + SX1262 LoRa 863-928MHz 8MB Development Board

ESP32S3 + SX1262 LoRa 863-928MHz 8MB Development Board

The ESP32S3 + SX1262 LoRa 863-928MHz 8MB Development Board is a compact IoT development board that combines long-range LoRa communication with Wi-Fi and Bluetooth connectivity on a single board. It utilizes the dual-core ESP32-S3FN8 as the main processor and the Semtech SX1262 for LoRa communication. The ESP32-S3 processor operates at a maximum frequency of 240MHz.

The board features a 0.49-inch, 64×32 pixel OLED display. This display allows system status, sensor readings, battery levels, or debugging information to be shown directly on the board. The Wireless Stick V3 is designed with a more compact physical form factor compared to classic WiFi LoRa 32 boards.

It supports 3.7V lithium battery connection.

The board features an integrated lithium battery management system that includes an SH1.25-2 battery socket, charge/discharge management, overcharge protection, battery level detection, and automatic power switching between USB and battery.
