E310-900T23S Wireless Serial Port Module Half-duplex Transparent Transmission
[Introduction]：E310-900T23S is a wireless serial module based on ON Semiconductor's AX5045 narrow-band Sub-GHz RF transceiver solution. Operating in the frequency band 900.0MHz to 931.0MHz (default 915.0MHz), it has functions such as half-duplex transparent transmission, wake-up on air (ultra-low power), relay and data transfer ( distance extension).
