APM MavLink to FrSky X8R S.Port converter

Posted by Rolf Blomgren on January 24, 2014 at 8:03am

Hi all,

I just bought an FrSky Taranis for my quad copter and needed to get the Mavlink data up on the Taranis LCD telemetry display. So here is my solution using a Teensy3.1 as a converter between MavLink and the S.Port on FrSky X8R.

See attached file below...

        народ, это уже устарело, Pixhawk могет сам посебе s.port, просто добавь воды, пардон инвертор.

Hi Rolf.

Can the Teensy LC from Sparkfun be used instead of the Teensy 3.2?

  Sure it can, but remember the lc board runs on 3.3v, so you will need a voltage regulator capable of supplying that...which us why I chose the 3.2 board on 3 of my models

    IO is only 3.3v tolerant but Vin is up to 5.5v. Our 'standard' wiring for this application powers the teensy from the receiver so LC should be fine without any modifications or extra regulators.
    
    LC is a good choice as it's half the price :)

      The LC also has a Vin level logic booster on pin 17 so you can control LEDs like the neopixels, pretty cool :)

      So should it work with the io from pixhawk without issue?

        Yes all pixhawk logic is 3.3v except CAN:
