Wio LTE Cat M1/NB-IoT Tracker

Seeed’s Wio LTE CAT M1/NB-IoT is designed for Low-Power Wide-Area Network (LPWAN) with CAT M1(eMTC) and NB-IoT combo module. Besides, It has an ARM Cortex-M4 MCU and GNSS module.

It’s Arduino and Espruino(JavaScript) compatible development board helps to track nearly any moving thing on the planet and then upload that data wirelessly. By integrating Grove connector, the Wio LTE CAT M1/NB-IoT allows for flexible communication solutions with Grove systems.

Wio LTE CAT M1/NB-IoT is well suited for outdoor projects where the device can connect to the satellite navigation system and provide a real-time location of the item it is attached to.

Wio LTE CAT M1/NB-IoT support Espruino(JavaScript) engine so that anyone can build IoT project rapidly, especially while you can use lot of resource of JavaScript community.
