The CC2500 NRF24L01 A7105 CYRF6936 Multi RF 4 IN 1 Wireless Module for DIY Frsky Flysky Hisky Devo DSM2 Transmitter integrates four RF chips (CC2500, NRF24L01, A7105, CYRF6936) in one single PCB board. It supports more than 10 different protocols while working with MCU board, such as Frsky, Flysky, Hisky, Devo, DSM2, V2x2 and so on. You can use Arduino Nano to DIY your own MCU board. It can also be used with Walkera Devo transmitter.

Features

• Arduino Pro Mini 5V/16MHz (protocols are used as witness the existing on board LED on B5 pin), can also use any setup with Atmega 328P/16MHz
• A7105 module (X7105-D03 PA/LNA module, V911,V939 harvested TX modules)
• CC2500PA/LNA module
• Nrf24L01 PA/LNA module
• Devo module (based on CYRF6936)
• AMS1117 -5V and AMS1117-3.3V, LDO voltage regulator or any other regulators over 800mA
• Resistor 20K (between NRF_CE pin to Vcc)
• Caps 22-47uF (3pcs on ldo´s)
• Rotary dip switch 16 positions or DIP switch 4 positions, required only in PPM mode (now in the serial mode with er9x/ersky9x/opentx, there is no need to use dial switch anymore) NumberNamePropertyDescription1VCCPower3.3V Power upply2GNDPowerGround3PE1InputSwitch for RF Chips, See the Truth Table4PE2InputSwitch for RF chips, See the Truth Table5CSN1InputA7105 Chip Select6CSN2InputCC2500 Chip Select7CSN3InputNRF24L01 Chip Select8CSN4InputCYRF6936 Chip Select9SCKInputSPI Clock Signal10MOSIInputSPI Input for Slave Device11MISOOutputSPI Output for Slave Device12CYRF_RSTInputCYRF6936 Reset16RFOIn/OutRF Signal, Connect to AntennaOthersGNDPowerGround StatusPE1PE2A7105 RF Signal to AntennaLow LevelLow LevelCC2500 RF Signal to AntennaLow LevelHigh LevelNRF24L01 RF Signal to AntennaHigh LevelLow LevelCYRF6936 RF Signal to AntennaHigh LevelHigh Level For more information, please visit the RCG forum: http://www.rcgroups.com/forums/showthread.php?t=2165676
