[Introduction]：E72-2G4M20S1C is a multi-protocol 2.4GHz patch-type wireless system-on-chip module independently developed based on the CC2674P10 produced by TI. The transmit power is 20dBm. It integrates an ARM microcontroller and a high-performance wireless transceiver. It adopts industrial-grade 48MHz high-precision low-temperature Drift crystal oscillator. CC2674P has great potential to become the wireless microcontroller of choice for future smart furniture, IoT transformation, and industrial automation. Since this module is a pure hardware SoC module, it needs to be programmed by the user before it can be used.
