iFrogLab LoRa USB Dongle Gateway V2 (LLCC68 Edition)

Ultra Long Range Transceiver 3 Km

🚀 V2 All-New Upgrade! Ultimate “Plug-and-Play” — No Setup, No Modification, Zero Threshold!

Upgrading to the new 2nd generation LoRa (LLCC68) USB Dongle, you will experience unprecedented seamless integration. We’ve hidden all the complex engineering inside the powerful dual-chip hardware, bringing you the purest IoT development experience:

• ✅ 100% Driver-Free, Instant Connection: Whether you use Mac, Linux, QNAP NAS, or Raspberry Pi, it’s natively supported. No driver installation required! Plug it into the USB port, and the system detects it automatically, saving you from tedious initial setups.
• ✅ No Complex Setup, LoRa Made Easy: The powerful built-in SONIX MCU (SNC73313) automatically handles all underlying LoRa transmission protocols and RF parameters. You don’t need to read heavy chip datasheets or understand complex LoRa concepts; just control it easily via a standard USB (UART) interface.
• ✅ “Zero” Code Modification, Seamless Migration: Whether for data transmission or remote control, the V2 version simplifies everything to basic UART serial commands. Your existing system architecture and code require no modification or rewriting. You can get your project online the exact same day you receive the hardware!

🌟 Core Features

• New Dual-Chip Architecture: Powered by Semtech’s new LLCC68 RF chip and Microcontroller, providing exceptional connection stability.
• Global Certifications: The module is officially FCC Certified and NCC Certified, making your commercial products more competitive.
• Superior Penetration & Long Range: Up to 3 Km ultra-long-range transmission. Signals easily penetrate building walls and floors (e.g., transmitting from the 1st floor and effortlessly receiving on the 6th floor), directly replacing legacy network technologies like Zigbee and Z-Wave.
• Rich IIoT Expansion Interfaces: Beyond standard UART, the new module’s underlying pins support multiple control interfaces including I2C, SPI, I2S, and PWM. It also provides a standard reference circuit design for RS485, commonly used in industrial automation.
• Extreme Power Saving Design: A dedicated V11 (1.10 – 1.19V) independent power supply pin significantly optimizes power saving efficiency during standby and active states, perfect for battery-powered IoT applications.
• 100% Made in Taiwan: Guaranteed quality you can trust.
