Poll: Power Supply Solutions for the small ESP as Sensor network

#1 Post by tozett » 02 Feb 2016, 09:30

tried to say all in the subjekt:

i am looking for good Power-Supply solutions for the small ESP,
if you distribute 15 pieces around the house.

should be small, sleek, maybe conform with the local regulaties, not too hot to burn down the house, ....

(at the moment i am testing with a breadboard power-supply to an ESP12,
where the am1117 DC-DC converter get very,very hot. not the best to put it in the wall)

pictures and all IDEAS very wellcome.

The MCP1702 used in JeeNodes and other circuits here at JeeLabs is a nifty little voltage regulator. It’s not particularly good for high voltages (limited to about 13V), but it has a very low idle current

some more ideas for circuits here: http://jeelabs.org/tag/power/

but a true solution has circut, case, and costs < 1 EUR
:mrgreen:

Hi,

I have orderered these power-suppliers:PowerSupply and then I want to go down to 3.3V with those: DCDC.

The power-supply was tested once from a danish expert: Expert.

But, all in all this comes up to 3€ per power supply. Thats far away from the 1€ supply that tozett mentioned.

I use the HLK for a while now and so far so good.
I just put a MOV across it, with a fuse.

Why should you not buy the 3.3v version? I have a couple of those, working great, no step down required.

Great, thanks. A few months back, when I ordered them, the only ones were 5 volt, but this is very nice.

this looks good to me,
a well sorted pcb with components from aliexpress.
only little to solder, if components break, i get new ones from china ..

maybe the PSU is only one part of a suitable complete "sensor-module",
this PCB layout seems also nice, compact and "suitable" for an good psu...

perhaps the PSU is just a single piece of a reasonable complete "sensor-module",

this PCB design appears to be additionally decent, reduced and "reasonable" for a decent PSU.
