Ebyte E70-400M14S1B TI CC1312R chip RF module Dual band high power wireless module With UART, I2C, SPI

Product introduction: E70-400M14S1B adopts the original imported CC1312R RF chip of Texas Instruments (TI), the chip integrates a single-chip microcomputer and wireless transceiver, and adopts 48MHz industrial-grade high-precision low-temperature bleaching oscillator to ensure its industrial characteristics and stable performance. The wireless module is a pure hardware SOC module, there is no program from the factory, and the user needs to develop it for secondary use before it can be used.
