[Introduction]：E310-433T23S is a wireless serial module based on ON Semiconductor's narrow-band Sub-GHz RF transceiver AX5045 solution. Working in the 425.0MHz to 450.0MHz frequency band (default 433.0MHz), it has functions such as half-duplex transparent transmission, air wake-up (ultra-low power consumption), data relay and forwarding (distance extension).
