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 •
