Update BOM_DIY_STM32 & Schematic.md

Browse Source 
Added Digi-Key shared carts for latest build BOM. 
Need to confirm if SV202,SV203, and SV204 each need a strip of 40 header pins for a total of 120 pins as currently since each S1011EC-40-ND part has 40  pins?

Digikey may not be your preferred supplier, but you should find enough information on their page to cross reference parts.
If digikey is your prefered supplier, their is a link to shared carts to make checkout easier at the begining of the BOM.
## IMPORTANT NOTE on Telemetry
In the case of the Turnigy 9X/9XR/9XR Pro you don't need to invert the telemetry signal therefore the instalation of the inverter chip SN74LVC2G86DCTR is **OPTIONAL**. In this case and in order to have telemetry you need to solder **SJ1/SJ301** on the back of the board depending on which board version you have.

Please Note - With the Digikey shared carts it is cheaper to order 10 piece stips with some parts like resistors and capacitors. These extra parts are not reflected or needed in the followong BOM list.
