2.4GHz Direct Sequence Spread Spectrum RF Module

This module can apply to wireless data two-way transmission. Frequency is 2.4GHz and takes Direct Sequence Spread Spectrum. Strong anti-interference, especially, it is less vulnerable to the wireless LAN, Bluetooth receiver, Wireless Network, Wifi, microwave ovens and so on. TRW-24DSHI two-way transceiver module is taking Direct Sequence Spread Spectrum (DSSS). You can get the highest reliability and high data rate performance by using variable phase modulation such as PSK, QPSK( Quadrature Phase Shift Keying),DQPSK(Differential Quadrature Phase Shift Keying) and so on. Advantage is it still can keep good communication during existing 2.4GHz wireless network in high-interference environment. Direct Sequence Spread Spectrum(DSSS) provides the maximum data transfer rate is 250Kbps, maximum transmitter power is +20dBm, working voltage is 4.3V~5.5V. Build-in UART Micro-controller interface. It can apply to various data transmission, short distance handheld device and corresponding application, such as wireless mouse, wireless keyboard, wireless remote controller, home automatically control, wireless toy and so on.
