HT-M02 Edge LoRa Gateway

Description

In practice, the working environment of the equipment may not be as good as expected, on the contrary, it may be very bad… For example, in the industrial environment, the site may have tremendous vibration, noise, dust, high temperature, and other issues. In the city environment, sunshine and rain, low temperature in winter, and high temperature in summer is always unavoidable……

HT-M02 considers and solves all the above problems and design strictly with industrial standards, Integrated Linux Operating System (4.14 Kernel, Debian Stretch 9.8). IP65 waterproofing, no fan or motor heat dissipation structure, 1-GHz Sitara™ ARM^® Cortex^®-A8 32‑Bit RISC Processor, 512MB DDR3, 4G eMMC. PoE power supply or 110 / 220V AC power supply (110 / 220V AC power supply version use 4G upload LoRa data).
