Ebyte E04-400M16S 433M/470M frequency SPI hardware RF transceiver module

[Introduction]：E04-400M16S is a high-performance ultra-low power wireless transceiver module. It is an ultra-small size patch-type wireless transceiver and transceiver module independently developed based on the S2-LPQTR chip of STMicroelectronics. It works in the 433M/470M frequency band and has a maximum transmit power of 16dBm. Since this module is SPI pure hardware
