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.

Muy buena venta y profesional. Gracias, Þorsteinn.

Very good and professional selling. Thanks, Þorsteinn.

La calidad de construcción parece buena. Tenga en cuenta que este producto espera entrada de 5V en el gato del barril también. El regulador reducirá 5v a 3.3v en el pin apropiado, pero sólo si usted introduce 5v! CUIDADO!!!

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!!!
