CC2500 NRF24L01 A7105 CYRF6936 4 In 1 RF Module For Walkera D7E D10 Transmitter Description: Item Name: RF module 4 In 1 Chip: CC2500, NRF24L01, A7105, CYRF6936 Compatibility: Supports dozens of protocols,such as Frsky,Spektrum DSM2/DSMX,Walkera Devo,FUTABAS SFHSS,Flysky,MJX,Esky,Wltoys,and etc. Features: 4 IN 1 RF module integrates four RF chips( CC2500, NRF24L01, A7105, CYRF6936 ) in one single PCB board. 4 IN 1 RF module came with 160mW ouput PA, LNA and high frequency signal switching circuit. Plug and use,can directly compatible with Walkera transmitter, no need to solder or update the transmitter firmware, and make the transmitter has longer control range and Improve power supply of transmitter. If additional welding 3 chip select signal and with DEVIATION open source firmware,this module can work with almost all the transmitter open source protocol.

Including but not limited to the following issues: - Part program version DSM2 have protocol compatibility problems. - Some receiver (original AR600) need to rebind per use,some receiver (Spektrum integrated receiver) frame rate is a bit slow. This issue basically determine the problem is on the program itself. Package Included: 1x 4 In 1 RF Module ,,,,,,,,,,
