Description Module COMX NBIoT is a stackable multi-band NB-IoT wireless communication module, equipped with the SIM7020G communication module. The module supports PSM and eDRX low-power modes. It also has wide signal coverage, and compared to GSM, NB-IoT has strong signal gain, which enables the product to have wireless communication capabilities in locations such as basements. The module comes with a DC power input, allowing it to be powered by an external power supply of 5 ~ 12V. For easy pin configuration, a DIP switch is used to set the pins. The SIM7020G module is an optimal solution for low-latency, low-power, and low-throughput applications, making it highly suitable for IoT applications such as smart meters, remote control, asset tracking, remote monitoring, telemedicine, and shared bikes. Compatibility When used with the Fire controller, due to PSRAM pin conflicts (G16/G17), please switch the module base DIP switch pins to TX(G0/G13) and RX(G5/G15).
