CC2500 PA LNA Romote Wireless Module CC2500 SI4432
A part of the review has been auto-translated.
Got this chip installed in a Devo 7e and couldn't be happier. The solder points were very small so do not attempt this unless you are confident with your soldering skills. You will need a pig tail that will hook up to the antenna port. Banggood also sells that. http://www.banggood.com/50cm-U_FLIPX-to-RP-SMA-Female-Antenna-Pigtail-Jumper-Cable-p-924946.html . You will also need to flash your Devo in order to use this chip. I have not had any range problems with it. I've gone out at least 250 meters so far before I ran out of flying field and never had any issues with signal. Using D4R-II RX.
Just solder this module in my devo 7e works perfectly with frsky receiver. It's definitely cc2500AND NOT nrf24l01
