Updating BangGood ATMega328P 4in1 multi protocol tx module firmware frsky taranis turnigy 9xr pro

4in1 Multi Protocol Module http://bit.ly/bg4in1module A guide to update the ATMega 328P, 4 in 1 multi module firmware from BangGood. I'd advising updating only if you really need to since you can potentially mess things up. "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)." 4in1 Multi Protocol Module http://bit.ly/bg4in1module http://amzn.to/2qmJLQ4 Multi Protocol TX Transmitter Module Case for FrSky FlySky http://bit.ly/bg4in1case FrSky Taranis Q X7 http://bit.ly/bgtaranisqx7 http://www.gearbest.com/multi-rotor-p...
