Solidly built dual input dual rail supply – Power 3.3V / 5V Supply Module for MB102 Bread Board Reviews

posted by xephris on 07/23/2013 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
- Solid and stable regulated power supply from ~12V or 5V to 3.3V/5V - Runs cool - The 3 pins on each rail for GND and 3.3V/5V are nice - 3.3V/5V switch is secure and makes it just easy enough to change but hard enough to accidentally screw it up
Cons:
- Lack of an on/off switch - The mini-USB port only uses the power pins, it doesn't "talk USB", so drawing more than 100~500 mA from some devices may result in the USB host shutting off the port
Other:
Unlike some other reviewers, the board I received looks like the one in the picture. So I guess DX has corrected this since then.
Bottomline:
For this price and size, it's a decent power regulator.
