3pcs Geekcreit® XN297L 2.4G Long Distance Ultra Low Power RF Module Wireless Transceiver Module

Specifications: Size: 30.25 8.5 1mm3 Model: KSL703B Working voltage: 1.9V~3.6V Application range: Wireless mouse / machine keyboard Wireless PC peripherals Active RFID Toys Remote consumer electronic equipment RF terminal 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. Adopt ASK demodulation mode, the receiving sensitivity reaches -110dBm; 2.4GHZ ISM bandwidth Code rate: 2Mbps/1MBbps Very low power consumption (normal temperature): Emission current: 14.8mA (P0=0dBm) Receive current: 17.5mA Shutdown current: 2.5uA Standby current: 0.9mA 1.9~3.6V power supply Auto Transceive data packet automatic retransmission Automatic packet processing 6 data channels 5V withstand voltage Lead number symbol Name 1 IRQ Interrupt signal, active low 2 MISO SPI data input signal 3 MOSI SPI data output signal 4 SCK SPI clock signal 5 CSN SPI chip select signal 6 CE Chip chip select signal 7 VDD power input 8 GND Ground Package Included: 3 x Wireless Transceiver Module
