XIAO ESP32S3 & Wio-SX1262 Kit with 3D case
Introduction
This device is based on XIAO ESP32S3 and Wio-SX1262 LoRa module. Coupled with an exquisite 3D - printed casing, it is equipped with an 868 - 915MHZ wide frequency range and 2dBi gain external antenna. It can support 2.5km single channel lorawan gateway and meshtastic communication. Through the GPIO port, it can be paired with GNSS modules and other additional modules.
Features
- High RF performance: Supports LoRa (862 - 930MHz), 2.4GHz Wi - Fi, and BLE 5.0 dual - wireless communication. When connected to an external antenna, it enables remote communication over a distance of 2.5km (LoRa) and 100m + (Wi - Fi / BLE).
- LoRaWAN Hub: Pre-flashed with Single channel LoRaWAN firmware, it is ready to work once powered on.
- 3D casing Design: Measuring 22x23x57mm, this device features a black ABS material with an extensive temperature range (- 40℃ ~ 100℃), making it ideal for outdoor and space - constrained projects.
- Powerful MCU Board: Incorporate the ESP32S3 32-bit, dual-core, Xtensa processor running at up to 240MHz, mounted multiple development ports, Arduino / MicroPython supported.
- Elaborate Power Design: Includes a Type-C USB interface, multiple GPIO/I2C/UART interface and lithium battery charge management.
- Versatile Hardware for Multiple Applications: Can be developed into a node or router for Meshtastic, a device for Single Channel LoRaWAN Gateway, or a LoRa & LoRaWAN sensor.
