I am making the Bus Pirate V4,but I don't konw the model of D1-D3 , Q1-Q2 and IC3. The partlist is only say that "200mA diode" and "PNP, 30hfe+, 800mA+" And the bom of Bus V4 sch have some thing wrong such as c7 and c8.
My job is very busy,I have three day time to do these in Ching Ming Festival.And I thought that I would do some changes for chinese user,because many elements are very hard to buy in china.
