Call 0345 2300 599The Seeed XIAO ESP32S3 Meshtastic LoRa Node is a compact, ready-to-use LoRa mesh device based on the XIAO ESP32S3 and Wio-SX1262 LoRa module.
Pre-flashed with Meshtastic firmware, this node is ready to join or create a Meshtastic mesh network straight out of the box. With support for 862-930MHz LoRa, 2.4GHz Wi-Fi, and Bluetooth 5.0, it is a flexible platform for off-grid messaging, portable mesh networking, embedded projects, and LoRa experimentation.
The device is supplied in a compact 3D-printed enclosure with an external 2dBi SMA to I-PEX antenna, offering a practical ready-built option for users who want a small Meshtastic node without having to assemble a board, radio module, case, and antenna separately.
Expansion and Development
The XIAO ESP32S3 platform provides multiple expansion options through its GPIO and interface connections. This allows the device to be paired with GNSS modules, sensors, or other additional hardware for custom LoRa and Meshtastic projects.
The ESP32-S3 platform also supports development using Arduino and MicroPython, making it a useful option for users who want to experiment beyond standard Meshtastic operation.
Important Note
Communication range will depend on antenna position, terrain, local interference, installation, and network conditions. The quoted 2-5km range is based on open-environment use and may be lower in built-up or obstructed areas.
Please ensure that the correct regional frequency settings are selected in Meshtastic before use.
