IoT Board Features


1. Dual network redundancy design, free switching inside and outside

The IoT circuit board is equipped with dual Ethernet interfaces and supports 10M/100M adaptive Ethernet dual network port switch function. The product can freely switch the transmission rate according to the transmission situation of the network card and the switch, and realize the arbitrary transmission of data between the same subnets.

2. Make communication possible "wireless"

The IoT circuit board has a custom dual-channel MiniPCIE interface, which can expand wireless communication modules such as GPRS/3G/4G, ZigBee, Lora, WiFi, GPS/Beidou, etc., and build a bridge between the local area network and the wide area network. Make communication "wireless possible, omnipotent".

3. Easy interface extension

The bottom plate of the IoT circuit board can be connected to a PACK board to facilitate the expansion of I/O ports, serial ports, CAN interfaces, audio interfaces, and isolated power supply interfaces. Users can expand according to actual needs to realize seamless connection between gateway controller and terminal products.

4. The bridge between IoT LAN and WAN

With its powerful performance advantages, IoT has penetrated into almost every area of our lives. From home remote monitoring, mobile payment, parking payment management, to vehicle location tracking, environmental monitoring, it is everywhere.


Main application areas: handheld mobile devices, industrial control, remote device monitoring, IoT applications, industrial sensors and controllers, portable wireless communication products, smart lights, home appliances
