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

some more ideas for circuits here: http://jeelabs.org/tag/power/
but a true solution has circut, case, and costs < 1 EUR

Look at wemos mini d1 : this is an esp board on the same seize of an SD Card, working on 5v true USB, lot of gpio aviable, all inside and got a 5v output direct from USB plug.

Re: Poll: Power Supply Solutions for the small ESP as Sensor network
i orderd some yesterday. How much current max on the 5v can they take, do you now?
you stated 750mA with leds..

but max? found nothing on their website.. i will see after they arrive in a month...

i don't know... as it looks like to be direct connect to the USB line, can expect thas this delivery the same as usb input.

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

Re: Poll: Power Supply Solutions for the small ESP as Sensor network
hey, this looks good. i think i will give this also a try.
the 1 EUR was not meant so straight literally, any small EUR will do..

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.ambassadoro wrote:Hi,

to have 5V for the ws2812b LED...?
but not always needed..

Re: Poll: Power Supply Solutions for the small ESP as Sensor network
Great, thanks. A few months back, when I ordered them, the only ones were 5 volt, but this is very nice.
Re: Poll: Power Supply Solutions for the small ESP as Sensor network
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 ..
