LTE-M Cellular Expansion Kit

Silicon Labs LTE-M Expansion Kit is an add-on board that features the XBee3® LTE-M cellular modem from DIGI® and is made for long rage, mobile and secure cloud-connected IoT. The expansion kit can plug into the EFM32GG11 starter kit (STK) and take advantage of the full-features of the low-power EFM32GG11 MCU. By pairing the low-power Gecko technology and peripherals with the secure, long-range connectivity of the XBee3® modem, battery-powered IoT is simplified.

The kit currently supports the EFM32GG11 Starter Kit (SLSTK3701), which is strictly required for running the software demos. (See compatible board tab)
