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 •

  Ø 6 data channels

  Ø 5V withstand voltage
