MCU_Board_B_v3.0.0b0

Because there're a lot of parts in the BOM, and it was during this time I started to feel the impact of the pandemi, which is the shortage of component in supplier (Digikey and Mouser). Some of my parts have leading time more than a month, while I need the board assembled as soon as possible, because I want to test it. But my experience was the communication with the sales and person in charge for assembly was quite easy, as I request to change 1 or 2 part number or asked for alternative component. Anyway while the shortage in component was really a nuisance, I think both designed and manufacturer are trying their hard to still cope with the production.
