ok non ancora testato ma tutto bene
item as described high/low pulse flashey thing (really weird description 30K not 33K resistance; looks like 510K and 30K wtf?) but none the less accurate. does not show blue dupont screw terminal connections. note that part of the board is blank in photo. never the less it was delivered in the package with items. so I was very pleased with that. the 22 UF capacitors are very well marked on this board. note other sellers made a huge mistake marking pcb backwards - but not this item awesome beans.
this little guy is very fun to experiment with. the blue leds are okay but it works with 5mm leds that are r/g/b or flash etc. use your imagination for led combos.
