The SX1262 included in the “Xiao nRF52840 & Wio‑SX1262 Kit” is not compatible with the Xiao ESP32S3.
This product is pre‑flashed with LoRa single‑channel gateway firmware, enabling quick setup through the SenseCraft app in just three steps. Meshtastic users should flash the appropriate firmware before use.
Featuring strong RF performance, it supports LoRa (862–930 MHz), 2.4 GHz Wi‑Fi, and BLE 5.0 for dual‑wireless communication. With an external antenna, it can achieve communication distances of 2–5 km (LoRa) and over 100 m (Wi‑Fi/BLE). As a LoRaWAN hub, it comes ready with single‑channel LoRaWAN firmware and starts working immediately once powered on.
The compact 3D‑designed enclosure (22 × 23 × 57 mm) is made of black ABS and withstands temperatures from −40 ℃ to 100 ℃, making it suitable for outdoor and space‑limited applications. Powered by the ESP32S3 dual‑core 32‑bit Xtensa processor (up to 240 MHz), it offers multiple development interfaces and supports Arduino and MicroPython.
Its refined power design includes a USB‑C port, GPIO/I2C/UART interfaces, and lithium‑battery charging management. This versatile hardware can function as a Meshtastic node or router, a single‑channel LoRaWAN gateway, or a LoRa/LoRaWAN sensor device.
