2.4G CC2500 A7105 Flysky Frsky Devo DSM2 Multiprotocol TX Module With AntennaDescription:The 4 in 1 wireless module integrate four RF chips (CC2500、NRF24L01、A7105、CYRF6936) into one single circuit board、with MCU baseplate、can support a variety of remote control protocols by identifying the PPM signal output of the remote control、such as Walkera DEVO、Spektrum DSM2、Flysky、Frsky、WLToys、Hubsan、Hisky、etc. It can control up to several hundreds airplanes (or receivers).This module can recognize the remote control PPM signal、 then converted into the corresponding standard wireless remote control format、which means that in theory as long as the remote control is with analog functions、 it can work. But this item didn't come with a housing、so you will need to solve the housing problem.This product includes the wireless module and the MCU baseplate. The wireless module is responsible for transmitting and receiving 2.4G wireless signals、the MCU baseplate is responsible for processing data and implementing remote control protocol、they should be used together.Specification:Item Name: 4 in 1 multi-protocol wireless moduleWeight: About 28gSize: 13*8*1cmBaseplate: Flysky、Frsky、JR (optional)Pin Function:          Number       Name       Property       Description           1       VCC       Power       3.3V Power supply           2       GND       Power       ground           3       PE1       input       Amplifier and antenna switching signal.
