                  Features:
                   
                  WL703B is a 2.4G short-range transceiver module with GFSK modulation. The module integrates RF transceiver channels, GFSK modems and data links. Users only need to make simple settings for the receiving/transmitting channel to communicate. In Auto Transceive mode, the chip can automatically judge whether the data is transmitted/received successfully according to the response information, thereby re-transmitting, losing packets, continuing to send and waiting, etc., simplifying the user program.
                   
                    Ø Adopt ASK demodulation mode, the receiving sensitivity reaches -110dBm;
                    Ø 2.4GHZ ISM bandwidth
                    Ø Code rate: 2Mbps/1MBbps
                    Ø Very low power consumption (normal temperature):
                  Emission current: 14.8mA (P0=0dBm)
                  Receive current: 17.5mA
                  Shutdown current: 2.5uA
                  Standby current: 0.9mA
                    Ø 1.9~3.6V power supply
                    Ø Auto Transceive data packet automatic retransmission
                    Ø Automatic packet processing •
