XIAO ESP32S3 & Wio-SX1262 Kit for Meshtastic & LoRa
The XIAO ESP32S3 & Wio-SX1262 Kit is a compact and versatile development board designed for building low-power, long-range wireless networks.
Ideal for applications like Meshtastic, LoRaWAN, and sensor-based projects, it combines the powerful ESP32-S3 microcontroller with the Semtech SX1262 LoRa module.
This combination enables seamless communication over distances up to 2.5 km using LoRa technology, along with Wi-Fi and Bluetooth connectivity for added flexibility.
Measuring just 21 x 18 mm, the kit is perfect for space-constrained environments such as wearables or remote sensor nodes. It comes pre-flashed with Meshtastic firmware, allowing for immediate use in mesh networking applications.
Additionally, the board supports Arduino development, making it accessible for both beginners and experienced developers.
With its low power consumption and robust wireless capabilities, this kit is an excellent choice for creating reliable communication networks in remote or challenging environments.

Hardware Overview
LoRa Range Test Results
The XIAO ESP32S3 Wio SX1262 Kit delivers strong long-range performance in open outdoor conditions. During field testing with Meshtastic firmware, the module maintained stable communication across:
- Urban Area: 1–1.5 km with buildings and interference.
- Semi-Open Areas: 2–4 km in mixed terrain with partial line of sight.
- Open Field / Rural Test: 5 km+ with clear line of sight and elevated antenna placement.
These ranges vary based on antenna type, height, obstacles, and transmission power settings.
