Meshtactic is ready to use out of the box: pre-installed Meshtastic firmware, it works as soon as it is powered on. Excellent RF performance: supports LoRa (862-930MHz) 2.4GHz Wi-Fi and BLE 5.0 dual wireless communications, supports 2-5km (LoRa) and 100m+ (Wi-Fi/BLE) long-range communication when connected to U.FL antenna. Powerful MCU board: integrated ESP32S3 32-bit, dual-core, Xtensa processor, running at up to 240MHz, installed multiple development ports, support for Arduino/for MicroPython. Exquisite power design: includes Type-C USB interface and lithium battery charging management. The same hardware is suitable for multiple applications: can be developed as a Meshtastic node or router, a single-channel LoRaWAN gateway, or a LoRa and LoRaWAN sensor. Compatible with XIAO expansion board to add screens and sensors, and add Grove sensors through Grove expansion board. ESP32S3: SP32-S3R8, Xtensa LX7 dual-core, 32-bit processor, running at up to 240MHz LoRa: Based on Semtech SX1262, supports 862-930MHz BLE: Bluetooth 5.0, Bluetooth mesh Wi-Fi: Complete 2.4GHz Wi-Fi subsystem The product appearance and printed words may vary depending on the batch, but this does not affect use.
