Features:
XL7105-SY is made by adopting high performance 2.4G wireless transceiver chip A7105 of Taiwan Shengke (AMIC)
Working in 2400-2483M international opened ISM band
The biggest transmission power is 0 dBm(1 mW )500 KBPS
The highest RX sensitivity is -99 dBm @ 250 KBPS,
The distance is as far as 120M
Built-in ID CODE WORD in IC,support CD (carrier detect), FEC error correction
SPI interface, independent 64 bytes RX and TX FIFO.
Cost performance is higher than NRF24L01 and CC2500
Note: this module needs 3.3V power supply, can use voltage chip to reduce the voltage.
Package Included:
1 x Transmitter Module
