NB-IoT+MCU Universal Application Platform Solution
The introduction of NB-IoT+MCU Universal Application Platform Solution
NB-IoT module, integrated with the Haisi boudica150 chip, can communicate with the carrier infrastructure through the 3GPP NB-IoT protocol, support 3GPP rel13/rel14, use BPSK and QPSK modulation, frequency range from 698MHz to 2180MHz, output power 23dBm, maximum Support for connecting 55,000 device units. Huada HC32L110 MCU, 32MHz Cortex-M0+ 32-bit CPU platform, 2us wake-up time from ultra-low power mode, system response is agile, current is only 6uA under 32.768KHz operation, with rich peripheral interfaces: UART*2, LPUART, I2C SPI, etc., can meet the low power application environment.
