About the Power supply PCB

Power supply is an open source PCB design by Ciprian-LocalPulse, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 55 mm, with 12 components from 11 distinct parts.

Other key parts include the AMS1117-3.3 and MC34063. By type, the board carries 3 diodes, 2 ICs, 1 connector and 1 inductor.

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

From the project

Open-source firmware and hardware design for EMP detection and active shielding of critical electronics.

Three PCB files, one per circuit schematic in hardware/schematics/, each with real component footprints placed on a board outline — not just a schematic-level BOM. No copper routing yet — that's a deliberately separate, not-yet-done step (see "Status" below).

- sensorconditioning.kicadpcb — 15 component footprints + 4 M3 mounting holes, 70×45mm outline. - actuatordrive.kicadpcb — 9 component footprints + 4 M3 mounting holes, 65×45mm outline. - powersupply.kicadpcb — 14 component footprints + 4 M3 mounting…
