Breadboard Power Supply Module 3.3V 5V 7-12V with USB port
I have used MB102 breadboard power supply module, but it don't have fuse on any rail and do not indicate voltages on 5V and 3.3V rails. There are also versions where full input voltage is available on USB port (7V and more).
On this module 7-12V can be set to output to breadboard, as well as, 5v and 3.3V. Left and right side are independent. All voltages are available all of the time. All rails are PTC fused, and voltage on rail is indicated with LED. LEDs are spread on board on purpose, user will see if PTC is "blown" on any rail or not. This module holds in breadboard very well, due to 4 rows of holding/supplying pins. All traces are 1mm width. There are vias under voltage regulators to cool them down a bit.
This module can supply full current of input power supply (max. about 0.8A due switch capabilities), and due to AMS1117 regulators max. 500mA on 5V rail (7V input supply voltage), and max. 500mA on 3.3V rail.
