All three pcbs tested and found working. Note that Pin marked as +5V is actually V input.

If powering by USB, the +5V is sourced from the USB and +5 is regulated to 3.3V output. BUT, the Barrel connector is directly connected to +5V output and this value regulated to 3.3V output. So, if connecting, for example, +12V to barrel connector, then +5V output will actually be +12V. Also, barrel connector is connected directly to USB so don't plug in USB at same time as barrel.

Molto buona e professionale vendita. Grazie, Þorsteinn.

Very good and professional selling. Thanks, Þorsteinn.

Attenzione che questo prodotto si aspetta 5V di ingresso sul jack canna pure. Il regolatore ridurrà 5v a 3.3v sul perno appropriato, ma solo se si immette 5v! ATTENZIONE!!!

Build quality seems good. Beware that this product expect 5V input on the barrel jack as well. The regulator will reduce 5v to 3.3v on the appropriate pin, but only if you input 5v! BEWARE!!!
