Radio module based TI wireless MCU CC1312R1.
N531BS integrated TI CC1312R1 chip, suitable for169M, 433M, 868MHz, 915MHz band. N531BS module has the characteristics of low cost, low power consumption and small size. Module is mainly for IoT, intelligent home, wireless meter reading, scientific research and medical treatment, and medium and long-distance wireless communication equipment. N531BS leads all pins out of CC1312R chip for secondary development. The UARTs implement universal asynchronous receiver and transmitter functions. They support flexible baudrate generation up to a maximum of 3 Mbps.
N531BS (CC1312R1) is suitable for free frequency band in EU and USA.
