[Introduction]:E70-400M14S1B adopts CC1312R RF chip originally imported from Texas Instruments (TI), which integrates single-chip microcomputer and wireless transceiver, and adopts 48MHz industrial-grade high-precision low-temperature drift crystal oscillator to ensure its industrial characteristics and stable performance. The wireless module is a pure hardware SOC module, there is no program in the factory, and the user needs to carry out secondary development before it can be used
