Description

This thumb-sized LoRa dev kit, featuring the XIAO ESP32S3 and 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, with compatibility for Arduino development.

Feature

🌱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.

🌱Same Hardware for Multiple Applications: Can be developed as a Meshtastic node or router, a single-channel LoRaWAN gateway, or a LoRa & LoRaWAN sensor.

Compatible with XIAO Expansion Board for adding screens and sensors, and add Grove sensors via the Grove expansion Board.The

SX1262 in the "Xiao nRF52840 & Wio-SX1262 Kit" IS NOT COMPATIBLE with the Xiao ESP32S3.

Support connecting an external high-performance LoRa antenna using an IPEX to SMA connector:

• FPC antenna included in package

• 2 dBi external antenna and SMA to I-PEX antenna cable.

• 3 dBi fiberglass antenna and RPSMA-K to U.FL RF cable
