Seeed Studio XIAO nRF52840 Module & Wio-SX1262 Kit
The Seeed Studio XIAO nRF52840 Module & Wio-SX1262 Kit is a powerful combination designed for modern IoT and wireless networking projects.
Featuring the nRF52840 module and SX1262 transceiver, it supports BLE 5.0 and LoRa (862-930MHz) for reliable, long-range communication with low power consumption.
This versatile kit is perfect for applications such as Meshtastic, environmental monitoring, sensor networks, asset tracking, and educational or innovative experiments.
It's compact design and robust features make it an ideal solution for developers, makers, and students exploring connected device projects.
Features:
-
Versatile Microcontroller: Incorporate the Nordic nRF52840 chip with FPU, working up to 64 MHz, mounted several development ports, supported by Arduino, CircuitPython, and Micropython.
-
Long-range: LoRa on the Semtech SX1262 supports the 868/915 MHz bands, providing powerful performance.
-
Dual-core communication: It supports Bluetooth and LoRa dual modes, allowing for cross-domain interconnection.
- The integrated antenna is 8mm × 22mm × 23mm.
BLE + LoRa Use Case Examples
The XIAO nRF52840 Module Wio SX1262 Kit combines ultra-low-power BLE with long-range LoRa, unlocking powerful hybrid IoT applications. Here are practical examples:
-
Mobile-to-Mesh Messaging: Use BLE on your phone to send messages to the node, which then relays them over long-range LoRa via Meshtastic.
-
BLE Sensor Hub + LoRa Uplink: Pair multiple BLE sensors (heart rate, temperature, environmental tags) and send aggregated data over LoRa to a remote gateway.
-
Wearable Beacon + LoRa Tracker: Use BLE for proximity detection and LoRa for transmitting location or status updates across kilometers.
-
Short-Range Control + Long-Range Reporting: Control smart devices locally over BLE while forwarding logs or alerts to a distant LoRa node.

Applications:
-
Meshtastic Node&Router: An extremely compact node that may be used as a portable device or a stationary router to expand the Meshtastic network.
-
LoRa/LoRaWAN Sensor: A little LoRaWAN sensor, excellent for those new to LoRa/LoRaWAN.
- When paired with a GPS module (such as the XIAO L76K), it can be used to track the movement of logistical vehicles, livestock, and important equipment. LoRa's long-distance coverage (2-5 km in urban areas and more than 10 km in suburban areas) can help to lower the cost of base station placement.
