XIAO ESP32S3 & Wio-SX1262 Kit Introduction
Introduction
This thumb-sized LoRa development kit, which consists of the XIAO ESP32S3 and the Wio-SX1262 LoRa module, is an ideal starter kit for Meshtastic and LoRa/LoRaWAN projects. Supporting WiFi, BLE, and LoRa, it includes a built-in power management chip and can be extended via IIC, UART, and other GPIO interfaces, and is compatible with Arduino development. The XIAO ESP32S3 & Wio-SX1262 Kit is a single-channel LoRaWAN LoRa module with a low price and high cost performance. It is suitable for application scenarios with long distance, low power consumption, and small data volume. It supports more than 30 node devices (depending on upload interval, data payload, etc.).
Seeed provides 3 applications for this XIAO ESP32S3 & Wio-SX1262 Kit.
- Using Meshtastic for network communication
- Configuring as LoRaWAN node
- Configuring as LoRaWAN gateway
Features
- Meshtactic works out of the box: Pre-flashed with Meshtastic firmware, it is ready to work once powered on.
- Outstanding RF performance: Supports LoRa(862-930MHz) 2.4GHz Wi-Fi and BLE 5.0 dual wireless communication, support 2~5km(LoRa) and 100m+(Wi-Fi/BLE) remote communication when connected with U.FL antenna.
- Thumb-sized Compact Design: 21 x 18mm, adopting the classic form factor of XIAO, suitable for space-limited projects like wearable devices.
- 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 and lithium battery charge management.
