LimStick
LimStick
A tiny linux and Wi-Fi connected IoT gateway for industry applications with the support of flexible wireless and field bus expansion

A small form factor with unlimited ambition, the LimStick is an extremely cost-effective IoT Gateway.It has one Ethernet port as well as a mini PCIe socket -you can use the device as a wired router with LTE backup via the nano SIM card slot. Beside these, the LimStick use an isolated RS485 and a RS232 to connect sensors in field applications.Various wireless sensors can also be supported via add-on cards inserted into the mini PCIe socket, such as Lora, Zigbee or 868 Mhz.

The LimStick connect field networks with a cloud or any IoT directed application. Furthermore,it also perform data exchange with the PLC and communicate IoT capable field devices directly at the same time,used as a industry’s  configurable, manageable, and scalable wireless gateway for industrial IoT applications.
