Ultra Low Power RF Module Wireless Transceiver Module ID: 1407282

Specifications:

Size: 30.25 × 8.5 × 1mm3

Model: KSL703B

Working voltage: 1.9V~3.6V

Application range:

Ø Wireless mouse / machine keyboard

Ø Wireless PC peripherals

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)
