After a small break I was finally able to continue working on the TI's and Würth Elektronik LED Roadtest+.
In this post I will just demonstrate the custom booster pack for my MSP430FR4133 LaunchPadMSP430FR4133 LaunchPad
BoosterPack
For this project I placed all the necessary components on a 20-pin booster pack designed using Eagle freeware.
Magnetometer was used in form of a breakout board that connects to boosterpack using 5-pin board-to-board connector.
Main battery voltage will be sensed using simple voltage divider (I will use 1% resistors) so it will not be extremely precise but good enough to let me know if I have to land the aircraft soon.
Current speed of each separate motor will be sensed using simple low-pass filters attached to each ESC input (PWM). I plan to visualise each motor speed using the same WS2812B LED strip.

Here's a short video demonstration of a 3 cell battery powered LaunchPad with BoosterPack.
Thanks to my 2 year old son's fast steps I had to slow the video a bit 
Taking this video was great!
Thanks!
