ThinkNode G3 ESP32-S3 Single Channel LoRaWAN IoT Gateway

The ThinkNode G3 is a compact single-channel LoRaWAN gateway for IoT applications by Elecrow. The gateway is based on the powerful ESP32-S3 dual-core processor with a clock speed of 240 MHz and the Semtech SX1262 LoRa transceiver. The integrated TCXO crystal oscillator ensures high frequency stability and reliable long-distance communication. Configuration is conveniently done via a web console using a smartphone or PC, without the need for special software.

Features:

• ESP32-S3 dual-core processor with 240 MHz and 8 MB PSRAM for powerful data processing
• Semtech SX1262 LoRa transceiver with TCXO for stable long-distance communication
• WiFi and Ethernet backhaul provide flexible network connectivity
• Web console enables easy configuration via smartphone or PC
• OTA firmware updates simplify maintenance and updates
• Low power consumption of only 110 mA for energy-efficient continuous operation

Application Examples:

• Smart home integration with LoRaWAN sensors for temperature and humidity
• Agricultural monitoring of soil moisture and weather data
• Building automation with door and window sensors over long distances
• Environmental monitoring for air quality and noise pollution in cities
• Asset tracking and logistics with LoRaWAN trackers
