We have three new boards designed with KiCAD:
BB-PWR-8009 is with input from 3 to 5.5V DC and convert it to 3.3V / 1.5A
BB-PWR-8113 is with input from 4.5 to 16V DC and convert it to 3.3V / 3A
BB-PWR-3608 is with input 5V and convert it to 12V or 24V /1A
All three boards have efficiency more than 90% and work from -40+85C, they snap to Breadboard power rails and are easy to integrate.
