IoTBase NBIoT-CN is a functional base specifically designed for IoT NB-IoT data transmission scenarios. The kit comes with a powerful core controller BASIC (built-in ESP32, integrated Wi-Fi), and integrates rich interface resources (I2C, UART, GPIO, RS485, etc.) to adapt to various industrial field protocols (such as ModBus). It has a built-in SIM7020C module, mainly covering the Chinese Cat-NB frequency band, and integrates an SMA external antenna interface to improve communication quality and signal stability. It comes with a multi-functional rail fixing base, perfectly embedded in industrial application scenarios.
