Teensy v3.1 - FrSky Smart Port Sensor Shield with addressable led output and telemetry port

-Allows for Smart Port Sensors to chain from the servo connector pins (marked) using arduino ide & serial monitor to log data info:

FrSky S-Port telemetry library - easy to use and configurable
http://www.rcgroups.com/forums/showthread.php?t=2245978

-=The only power that’s needed is usb while chaining sensors=- Disconnect Board Power while USB connected and vice versa

-Working on teensy code for outputting data to onboard telemetry radio port

-Addressable led output to run led code if implemented for gps lock ect

-cut trace resistor(1k) pad for led output

-end mount 1000uf Capacitor pads for mounting

Very nice.  Where are those RGB LED boards from?

  Are you sure? yes | no

Charles Lakins wrote 04/25/2016 at 19:43 point

I added the info in the build instructions above :)

  Are you sure? yes | no

Im not the best at combining arduino code, i'm still working on trying to do so

  Are you sure? yes | no
