Vszerda XIAO ESP32 S3 Development Board Kit with Wio-SX1262

SKU CH-RFQB-2MHDM

Development kit with ESP32-S3 and SX1262 LoRa radio for Meshtastic networks

  • ESP32 S3 dual-core 32-bit processor handles complex IoT tasks
  • SX1262 LoRa radio enables long-range Meshtastic communication
  • Wio module integration simplifies sensor and actuator prototyping
  • Compact development kit accelerates LoRaWAN application deployment

ESP32-S3 kit with SX1262 radio

The Vszerda XIAO ESP32 S3 Development Board Kit integrates a dual-core 32-bit processor with a Semtech SX1262 LoRa transceiver. It targets makers building Meshtastic nodes or custom LoRaWAN endpoints who need a compact, breadboard-friendly platform. The board exposes GPIO, I2C, SPI and UART pins for sensor expansion.

Meshtastic-ready with LoRa headroom

The SX1262 front-end delivers long-range sub-GHz coverage for mesh messaging and telemetry. Firmware fits comfortably in the 32 MB flash, leaving room for application code and OTA updates. Projects requiring higher data rates, cellular backhaul or integrated GPS will need additional modules.

Questions about this item

Will the XIAO ESP32 S3 board work with my existing LoRa sensors that use the SX1262 chip?

Yes, the kit includes a Wio-SX1262 module so it can communicate directly with other SX1262-based LoRa devices on the same frequency and settings.

How can I verify the ESP32 S3 and SX1262 are functioning together after I flash Meshtastic firmware?

Open the Meshtastic mobile app via Bluetooth, check that the device shows a valid LoRa region and channel, then send a test message to confirm radio transmission and reception.
