Hello everyone,

i starting to build pcb with arduino (mysensors & Co) but i'm having a hard time finding the best (cheapest) way to get a reliable power supply converter...

for the moment i'm using phone charger than i strip down to get only the circuit board and then plug it into my pcb into my power lines ... that's not very practical but after many research i didnt find what i was looking for ... can you help me please ?

i'm looking for power supply converter that doesnt necessary give me a lot of amps but can :

220V => 5V 2/3A

i'm not confortable about building my own converter ...

thanks for your help!

Thanks for the answer :slight_smile:

but it's not really cheap, around 30€ ... :cry:

my usb charger system is cheaper ... can't believe that doesnt exist cheaper :confused:

You can't fight economy of scale. If you want cheap then you have to put up with the same unit that thousands of other people use.

Honestly a plugpack or "wall wart" is the safest way to do it.

Of course it does. But you really do get what you pay for. The power supply that you said is 30€ is a medical grade supply which is total unnecessary.

Your best option is to keep the 230V mains out of your device entirely. A 5V/2A wall wart with agency approvals can be had for less than $10.00. There is very little demand for board mount mains powered supplies, it's simply not what the electronics industry is using today in quantity which is why the prices are higher.

Yeah, you can find some on eBay for really cheap. But honestly, they're pretty crappy. That's why they're cheap!
