SI4432 Wireless Modules / SI4432-B1-FMR/470MHZ/433MHZ/915MHZ
Introduction:
- Has been to focus on the development and application of wireless transmission, with many experienced R & D engineers can provide a variety of wireless data transmission module, the SI4432 Wi block / SI4432-B1-FMR is a Division I for the long distance data transmissionspecially developed high-power and high sensitivity wireless module. SI4432 wireless chip work at 240MHZ-960MHZ, peer-to-peer applications, can also be composed of a star network, this module SI4432 data transmission module design frequency 470MHZ, RFmatch the debugging part,
- the Division has done a lot of optimization, making the emission efficiency of the highest harmonic minimum, making the the SI4432 wireless module to reach the minimum of outside equipment, radio frequency interference, while not susceptible to interference with other devices, greatly improvethe stability of the module transmit power up to 19.6dbm, the receiver sensitivity is-113dbm (9.6K rate test), measured with spring antenna distance of 10 meters, external 5DB cylindrical antenna distance can reach about 1600 m, the spacing of the pins for1.27mm PCB design more compact of the MCS51 test procedures and test board, and C8051F920 and nRF24LE1, SI4432 the test program, as well as the original provided EZMacPRo documentation and related procedures, as well as Si443X register set EXCEL documents,make application SI4432 simplistica
