Permanent power supply modules for Pro Mini?

Using Arduino General Electronics

Hi

I have currently modified my espresso maker with an UNO to control boiler temperature using PID, and also bluetooth connectivity for monitoring/changigng settings.

At present my UNO is external and powered via a USB mobile charger.

I have purchased a Pro Mini (5V) and want to integrate the board inside the espresso machine, to make it more WAF friendly. I also want to free up the wall socket, so im looking at options for powering the Pro Mini from the 240V currently present in my espresso machine.

I could solder some leads to the phone charger and use that, but want to first check if the community has some cleaner options. Preferably a ready made module with solder pads or screw terminals on the 240V side. Since this will be inside the espresso machine, a somewhat waterproof enclosure sounds like a good idea..

Does the community have some ideas for me?

I don't know where you're at, but something like this may be an option.

More something like this:

But i'd rather have it in a (semi) sealed module, because of water leakage risk..
