Description

IoTBase CatM is a functional base specifically designed for IoT data transmission scenarios. It integrates the SIM7080G communication module, supporting both CatM & NB-IoT modes with coverage for most CatM & NB-IoT frequency bands worldwide, meeting the needs of different regions and various communication rates / throughput requirements. The base integrates rich interface resources (I2C + UART + GPIO + RS485 + battery power interface) for easy expansion with various sensors, compatible with industrial protocols such as ModBus. It is very suitable for IoT applications such as remote control, remote monitoring, and telemedicine.
