NB IoT Development Board with Low Power Wide Coverage

SIM7028

SIM7028 is a multi band NB IoT wireless communication module, packaged in LCC+LGA. This product supports a maximum downlink rate of 125Kbps and a maximum uplink rate of 150Kbps.

SIM7028 has rich hardware interfaces, including serial port, GPIO, ADC, etc., which make the module have rich scalability and provide great convenience for user product development.

The packaging of SIM7028 is compatible with SIM800C and SIM7020. This also maximizes the investment efficiency of customers and shortens the time to market.

The SIM7028 module is the optimal solution for low latency, low power consumption, and low throughput applications, making it highly suitable for IoT applications such as metering, remote control, asset tracking, remote monitoring, remote healthcare, shared bicycles, and more.

Product advantages

Low power consumption: The module supports PSM low-power mode, and theoretically, two No. 5 batteries can support 10 years

Wide coverage: Compared to GSM, NB IoT has strong gain and wide signal coverage, which also enables the product to have wireless communication capabilities in locations such as basements
