Overview

Osiris PDB RevA is an open-source printed circuit board by JaredGarza, from the JaredGarza/Osiris_PDB_RevA repository on GitHub. It is a 4-layer board of 127.5 × 65 mm with 69 parts on 36 nets, routed with 299 tracks and 205 vias.

It is built around the 74AUP1G07GW,125-JSM, LT3010EMS8E#TRPBF and LTC4359IMS8#TRPBF, with the LTC4368HMS-1#TRPBF, B32529C0105J189 and RC0805FR-0710KL among its other parts. Its parts include 21 resistors, 19 capacitors, 5 ICs, 4 diodes and 4 connectors.

Osiris PDB Rev A

This repository contains the current KiCad 10 power distribution board project. Open Osiris_PDB_RevA.kicad_pro to edit the schematic and PCB. The Libraries and Datasheets directories contain project resources; keep them alongside the project files.

The PCB is the compact layout restored on October 1, 2026: J1 is on the left, J3 is on the right, and the ESC capacitor sits above the central circuitry. The schematic uses the matching connector and net assignments. Local library names and resource paths are configured for this project directory.

This revision is a prototype. Manufacturing preparation on October 2, 2026 resolved the redundant output-copper zone, improved J4 mounting-slot annular rings, filled missing part selections, and tightened silkscreen checks. Final checks report no schematic electrical-rule violations, no PCB design-rule violations, no unconnected PCB items, and no schematic parity issues.

The JLCPCB prototype quotation package and release review are in outputs/manufacturing-review-20261002. Exact JLCPCB parts matching, assembly-preview approval, and stackup/panel confirmation remain necessary before ordering. The 60 A continuous / 100 A for 30 seconds ESC targets still require physical qualification. Use the new manufacturing BOM for this design; the older cost workbook does not include every current selection.

The updated purchasing and cost workbook, with engineering, purchasing, and missing-link previews, is in outputs/updated-board-20261001. Component datasheets and local KiCad libraries are kept with the project. Temporary generation scripts, bundled software dependencies, and intermediate inspection files are excluded.

Questions

How big is the Osiris PDB RevA PCB?

It measures 127.5 × 65 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Osiris PDB RevA use?

69 parts, built around the 74AUP1G07GW,125-JSM, LT3010EMS8E#TRPBF, LTC4359IMS8#TRPBF and LTC4368HMS-1#TRPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Osiris PDB RevA KiCad files?

From the JaredGarza/Osiris_PDB_RevA repository on GitHub, at the commit this page was made from: the board is outputs/manufacturing-review-20261002/source_snapshot/Osiris_PDB_RevA.kicad_pcb and its schematic Manufacturing_REV1.1_5_Boards_2026-10-15/Source/Osiris_PDB_RevA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Osiris PDB RevA design in my own project?

Its repository states no licence, so its author keeps all rights: ask JaredGarza before reusing the design.
