Easily add USB power to low voltage HVAC wiring

This item is perfect for powering my Ring Alarm keyboard from the same 24V AC source that powers my Ecobee thermostat. I simply cut off the micro USB cable for power only, plugged it into the output and set it to 5.2V.

Pros
  • Comfortable
Cons
  • No power

Good to use with AC or DC input.

I haven't tested these yet but it seems like a good device. The fact that they are adjustable from 3.3V DC to the DC power rail is a plus, but the wide input voltage range makes them attractive for use in an existing AC or DC power system. I suggest paying attention not to exceed the input voltage or rated current as well as the output current.

Pros
  • Good performance
Cons
  • I don't remember but there was something

Easy to set up, dips under load

I'm using this to power a relay and an xbee to build a Zigbee enabled irrigation controller. I have a 40VA 24VAC transformer feeding a buck converter that I have set to 5VDC. It was easy, using a multimeter to set the appropriate voltage to test the output and my fingernail to turn a small screw. I'm deducting a star because when I hooked up the Raspberry Pi 3 I saw the voltage drop under load enough to complain of low voltage.

Pros
  • Free for educational purposes
Cons
  • Ugly packaging

Good layout, can get hot

Works as advertised. Strangely, my two boards weren't separated by a V-groove. If yours arrives this way, be careful not to bump yourself or unnecessarily bend the circuit boards when separating them. To test, I applied 24VAC to the device, set the output to 12VDC, and charged 2A and 1A each for about 15 minutes. No significant output ripple under any load. The heat was roughly evenly distributed across the rectifier (BR1), inductor (L1), and diode D1. In Test 2A they reached about 160F (71C)…

Pros
  • This is amazing
Cons
  • Out of fashion

The board works great. Be careful of its size.

I've used one of these in a project where there wasn't much space. To make sure it would fit I made a paper template footprint of the board and then measured the highest component on the board (it was the capacitor). Since this panel was assembled in a steel base unit, I glued a couple of "standoffs" to the bottom corners of the panel and then hot glued the whole thing to the steel base. It worked great and there was no chance of a short circuit. The payment worked well. Adjusting the DC output

Pros
  • Hands-free
Cons
  • Basically ok, but...
