About the PSU PCB

PSU is an open source PCB design by domesticmouse, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 28 × 110 mm, with 28 components from 17 distinct parts.

Other key parts include the K7812-1000R3. By type, the board carries 7 capacitors, 5 test points, 4 connectors, 4 diodes, 3 resistors and 2 ICs.

It belongs with the power & battery and audio designs in this gallery.

From the project

A simple Eurorack power supply. Just +12v and -12v rails. Nothing fancy.

A simple 6HP +-12V Eurorack PSU, based on Winterbloom's [Micronova][]. See [EurorRack dimensions][] for faceplate dimensions.
