Thanks esa, good points as well.
P1) You're absolutely correct in regards to the MW, but that's only one type of product. I have several others that don't have a built-in LDO (and I'm sure there may be others out there with similar circumstances). I had built this board for my own project consumption, but then several people asked to buy it, and thus it emerged. Also, keep in mind that this was a few years ago I popped this board out. I occasionally think of improving it, but then there are soooo many other ideas to chase after.
P2) I'm in the process of rebuilding the MW portal page, which will have all the schematics to the various versions available. The schematic posted on that page is the original version of the MW-12B/CW, which had VCC on the FTDI header. I noticed this was less than optimal, so ALL other versions of MW have this as a VIN pin. NOTE that ALL newest versions of MW-12B/CW also have this pin as VIN.
P3) here you go...
All the best..
