"Nice Work. I also built his copter. Aside from the frame plates he sells, I hand crafted the camera vibration mount out of carbon fiber and a dremel(Pain in the ass) If I crash beyond recognition I will use your method."
"Very Clean! Is your mag under the GPS? FYI, I had issues with mag interference and it turned out to be the metal screw used to attach the mag/GPS pod to the DIY lollipop standoff."
"For people just trying to get by (new to data-communications) this info is priceless as it's not stated in the FrSky instructions. Or at least I didn't read it that way. Thanks."
"I did some testing and discovered that both 5V and 3.3V FTDI adapters work. The trick is to have the ground connection from the FTDI (required). First I tried a 5V BEC from an ESC without success but discovered that adding the ground connection…"
"Thanks Guys. FYI. I used the Sparkfun FTDI - https://www.sparkfun.com/products/9115
This has both 5V and 3.3V, I saw Sandro's FTDI is 3.3V so tried the 3.3V setting. Without a 6V BEC it worked.
I was getting the UID # every time but perhaps the…"
"It Worked! My FTDI has both 5V and 3.3V for TX & RX signal(Via jumper solder pad). 3.3V Worked. Additionally I used Ground and 3.3V Power from the FTDI in lieu of an external BEC(Didn't work at first). Thanks!"
"Sandro, I was reading that your cable outputs 3.3V for TxO/RxI, and 5V for Power. Do you think the flash issue could be caused from an FTDI cable that outputs +5V for TxO/RxI?"
"I found the how-to instructions in the readme file: (i.e. For D4R-II it's required to jump Ch. 1 + 2 signal, and power to Ch. 3 or 4).
However I also cannot get past 2%. On the first try it would not go past 26%, 2% thereafter. Instead of using an…"
"Thanks Much. I wasn't sure if it was as simple as connecting the inverted TX/RX and Power(One way or the other).
I guess the "AD2" may be for other Telemetry stuff.
That makes sense. Thanks for the help."
"Let me clarify, The data port on the receiver has Gnd, AD2, Rx, and Tx. Of these 4 pins on the D4R-II Data Port, what is connected to the FTDI Adapter? In other words, On your set-up do you just have the inverted Tx/Rx, Ground and +5V jumped…"
