Description
ThinkNode G3 is a high-performance, compact LoRaWAN gateway designed for IoT communications. It uses the ESP32-S3 dual-core processor and Semtech SX1262 transceiver, equipped with a 240MHz dual-core main control, integrated Bluetooth, WiFi and optional 4G modules, and provides flexible network backhaul methods. The SX1262 transceiver, combined with the internal TCXO crystal oscillator, ensures ultra-long-distance transmission and high-frequency stability while maintaining low power consumption.
Supports US915MHz/EU868MHz frequencies and seamless conversion between LoRa and IP protocols, efficiently receiving LoRa signals and transmitting them back to the cloud through multiple networks. The simple configuration interface supports quick adjustment of LoRa parameters on mobile phones or PCs, and supports remote firmware upgrades.
