5V power supplies for sale, $1

Jarrett · October 7, 2021, 7:30pm

Hi all,

I’ve got some AC-5V modules. A couple hundred.

The part number is ZWS15-5. They can source 3A, good for powering Raspberry Pis, or whatever else. AC cable not included!
I was able to tune one down to 3.6V, which is the upper limit of what ESP32s and other small microcontrollers can handle, but that is unsupported, and might end poorly! But it will sometimes work, in some circumstances.

Please buy lots, they are forcing me out of my home. Cost is $1, payable to VHS.

Now if only you could pare down your couple hundred snowboards…

I’ll take… five please

hectorh · October 8, 2021, 4:33pm

10 for me as well

packetbob · October 8, 2021, 5:03pm

I grabbed 30 and left $30 in the donation box…
Note that:

There is a ton of cardboard dunnage used in packing these so please take some with you to avoid the Space having to deal with all of it.
There are only 40 (packed in 2 boxes of 20) in each larger box so that means there are 50 left (just so @Jarrett knows)

Thanks @Jarrett as these are extremely handy…

Jarrett · October 8, 2021, 5:12pm

Sweet, thanks, will replenish

SteveRoy · October 9, 2021, 2:09am

mike · October 27, 2021, 4:58pm

Janet · October 28, 2021, 1:39am

I’m pretty sure the power supply well is bottomless at this point.

winegummo · October 28, 2021, 2:28am

i just picked up 10 as well and there was still a ton

side question. what are connectors needed for these?

Rob_MacKenzie · October 28, 2021, 2:37am

BOX!
I made a box to put these in. I didn’t put in/out holes, since i figure people will want to add those themselves based on what cords are used. I just drilled out the hole on mine and soldered right to the pins.
