IoTBase NBIoT

SKU:K064

Description

IoTBase NBIoT is a functional base specifically designed for NB-IoT data transmission scenarios in the Internet of Things (IoT). The kit comes with a powerful core controller BASIC (built-in ESP32, integrated Wi-Fi), and is equipped with rich interface resources (I2C, UART, GPIO, RS485, etc.), supporting various industrial field protocols (such as ModBus). It includes a built-in SIM7020G module, covering most Cat-NB frequency bands, and integrates an SMA external antenna interface to enhance communication quality and signal stability. The kit also includes a multifunctional rail mounting base, perfectly embedding it into industrial application scenarios.
