LoRa module is optional

LoRa modules are optional and can reduce a lot of costs if you don’t need a LoRa module.

Highly extensible

Vision Master T190 has a rich set of pins and hardware resources, which will allow you to expand widely. The SH1.0-4P interface can be directly connected to the QuickLink series sensors.

Plastic support plate

A transparent plastic support platform is installed between the PCB and the display frequency, which can protect the electronic components on the board and enhance the heat dissipation function of the board.
