Native KiCad schematic and four-layer PCB draft for a regulated 12 V input with separate 5 V and 3.3 V buck converters. Designed as a documented portfolio project; not a fabrication release or tested hardware.
Open it
- Install KiCad 9 or newer, including its standard applications.
- Extract this entire ZIP. Keep the project and Libraries folder together.
- Open
Agrobot_Power_Board.kicad_proin KiCad. - Open the schematic with the Schematic Editor button, or the board with the PCB Editor button.
- In PCB Editor, press B to fill the ground zones, then save. If any load/parse error appears, stop and send a screenshot of the complete error.
- Press Alt+3 for KiCad's 3D viewer. Included 3D bodies are simplified representations, not manufacturer CAD models.
Ground zones have been defined but are delivered unfilled. Until step 5, ground connections will appear incomplete. The supplied images and PDF are authoring previews, not screenshots or exports from KiCad.
Requirements and status
| Item | Target / implementation | Evidence status |
|---|---|---|
| Input | Regulated 12 V DC, screw terminal | Nominal design input; not qualified for battery/automotive transients |
| 5 V output | 0.75 A continuous, 1.5 A peak | Design target; load and thermal testing pending |
| 3.3 V output | 0.5 A continuous, 1.0 A peak | Design target; load and thermal testing pending |
| Ripple | 20 mVpp / 10 mVpp respectively, 20 MHz bandwidth | Targets only; not simulated or measured |
| Protection | Resettable input fuse, reverse-polarity diode, TVS clamp | Component-level proposal; coordination review pending |
| Board | 96 x 78 mm, four copper layers, four 3.2 mm mounting holes | Native layout draft |
| Ground | Two internal planes plus outer-layer zones | Fill locally before native DRC |
The two LMR33630 converters use separate inductors, feedback networks, and output capacitors. No microcontroller or sensors are included: this is the Agrobot power-conditioning board only. Peak duration is unspecified; no guaranteed peak-duration capability is claimed.

Publishing on GitHub
Upload this folder's contents after reviewing the design. Keep the libraries and relative folder structure intact. The included .gitignore excludes local report runs and editor backups. You can deliberately add selected native PDFs, renders, and reviewed reports later.
An accurate project description is: "Developed a KiCad power-conditioning PCB draft for a 12 V input and 5 V/3.3 V outputs, with input protection and documented load/ripple targets. Fabrication and bench validation pending."
Do not describe the ripple or current targets as measured results, or this project as completed in Altium. AI-assisted authoring should be described accurately when relevant to portfolio or academic requirements.

Questions
How big is the Agrobot Power Board PCB?
It measures 96 × 78 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Agrobot Power Board use?
41 parts, built around the LMR33630ADDA. 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 Agrobot Power Board KiCad files?
From the jchik1102/Agro-PCB repository on GitHub, at the commit this page was made from: the board is Agrobot_Power_Board.kicad_pcb and its schematic Agrobot_Power_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Agrobot Power Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jchik1102 before reusing the design.
