3pcs 5V Mini USB Power Connector DC Power Socket Board
A part of the review has been auto-translated.
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.
It does what it is supposed to do.
Very good and professional selling. Thanks, Þorsteinn.
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!!!
