  • Sorry if these are old questions but I could not find them in the discussion:

    On the schematic, what is U4? and what are the pin numbers? Are there any specs on the power supplied via Vcc? I see that internal power is 3.3v so presumably the input must be higher due to regulator drop out (even on an LDO)

No public wish lists :(
