MicroBBPS
About the MicroBBPS PCB
MicroBBPS is an open source PCB design by stasiselectronics, published on GitHub. It is a 2-layer board measuring 54 × 24 mm, with 21 components from 13 distinct parts.
Other key parts include the NCP1117ST50T3G and NCP1117ST33T3G. By type, the board carries 8 capacitors, 6 connectors, 3 diodes, 2 ICs and 2 resistors.
It belongs with the power & battery and dev boards & breakouts designs in this gallery.
From the project
Small breadboard power supply that offers MicroUSB connector for 5V power, a screw terminal for max 20v DC power. Select between 5V, 3.3V or Vin for each power rail.
A small, Micro USB connected power supply designed to fit onto the power rails of a solderless breadboard.
For each side, you can select between 3.3 & 5.0 Volt linear regulators, or the input voltage at the screw terminal.
The integrated version adds 26 breadboard rows and 2 continuous power rails. So you can turn those prototypes into something more permanent with an easy microUSB power connector.
