5/5 units were dead, tested with both 9V battery and USB power. DO NOT BUY!

5 for 5 work at both 5V and 3.3V with a 9 volt battery as the supply. No complaints here as long as they hold up.

They work as expected and tested with multimeter. Good packaging.

I swapped out the capacitors, measured values/esr's were a bit wonky on a couple and I had a pile of know good caps. But mostly those caps were 105c, and small based on voltage/mf rating; think expensive if reputable. These boards are not expensive. Now they really are 105c.

I tested all 5 power supplies and all were within 1% of the nominal voltages. They all fit my breadboards perfectly. Quite handy while prototyping, whether it's a 5v or a 3.3v project.

Al momento de insertarlas en el protoboard los pines se despegan del pcb y dañan las conexiones, de los 5 se me dañaron 3

These seem very sturdy and because they are HiLetgo, I trust that the electronics are safe and good quality.They attach well to the breadboard and don't take up much space.They are versatile, as you can have either 5V, 3.3V or both fed to the breadboard. They also have additional power pins that you can use without the breadboard.It's very handy to have the power switch, so you can just power things off right at the breadboard.The packaging is lacking some as some of the pins were bent when it arrived. I straightened them out and things are still working. It is a little worrisome that this may have created a weakness that will cause problems later on.The only disappointment I've had is that it consumes part of the power. I should have realized this. It turns out that I need 7.5V coming in to get a full 5V of output. After switching to a better power supply, I'm fully satisfied.I'd recommend this highly.

You can find the schematic online, but that didn't help me decipher how this board works. Here's the scoop:- the board is silk screened "HW-131", though Hiletgo doesn't refer to it that way- the barrel connector apparently must be attached to a 6.5-9V DC power supply. (If you connect the barrel connector to a USB power supply, the board will supply only either 3.3 or 2.5 volts, depending on your shorting pin placement.)- the USB connector is a power INPUT, which likely will require you to obtain a USB Type A male > Type A male cable, and obviously, a 5V USB power supply.- the 4-pin headers on each side of the board allow you to select the voltage for that half of the board; you can independently choose two voltage outputs.- the headers are labeled somewhat confusingly "5V OFF __ 3.3" (one pin has no label).- applying the supplied shorting pins across "5V" and "OFF" gives 5V out for that side of the board.- applying the supplied shorting pins across the unlabeled and "3.3" pins gives 3.3V for that side of the board.I'm happy with the product, but it's a shame Hiletgo can't list some simple instructions.
