Design with control
Place parts, route copper, shape the board, use layers and grid snap, and tailor navigation, colors, keys, and panels to your working style.
professional electronics design platform
Design the board. Write the firmware. See it work.
Unmild Designer brings PCB layout, embedded C/C++ development, microcontroller behavior, 3D verification, analysis, and manufacturing release into one serious Windows desktop workflow.

special features
Mool and Live 3D: the board, code, and behavior in one view.
Mool is Unmild Designer’s embedded-development environment. Write C or C++ against the microcontroller placed on your board, build it through your installed toolchain, create the required binary image, and watch the design respond in real time. Live 3D keeps the physical board visible while behavior, readings, and issues evolve.
- Author embedded C/C++ in the same project as the PCB
- Build firmware with your local compiler and generate board-ready binary output
- Program the selected microcontroller and observe pins, behavior, readings, and faults alongside the 3D board
purpose-built desktop EDA
A serious workflow, from first trace to fabrication handoff.
Professional electronics work moves from intent to layout, firmware, behavior, verification, and release. Unmild Designer is organized around that complete decision path.
Program in context
Use Mool to write embedded C/C++, build the selected target, program the microcontroller, and observe its behavior in the same design environment.
Release with confidence
Move from verified design to complete manufacturing output, documentation, review material, and release information without breaking the workflow.
Design, verify, run, export
One connected workflow for board design, embedded code, behavior, verification, and manufacturing.
Design
Place parts from the built-in library, route traces with the wire tool, and shape the board outline.
Verify
Review the board in 3D and run the current basic PCB DRC and schematic ERC checks before release.
Program
Write embedded C/C++ with Mool, build target-ready binaries through your local toolchain, and program the microcontroller in context.
Release
Generate the complete package for manufacturing, review, and handoff in one professional release workflow.
Review behavior where the board is being designed.
Run gives supported components a visible state on the board and reports concrete readings and problems. In this example, it identifies an LED current issue and suggests a series-resistor change — useful feedback while the layout is still open.

A parts library that comes when called
The component picker — internally named Saad, Sanskrit for "to call" — searches by part, value, or package and drops it wherever you click. No hunting through nested menus mid-layout.
- Search across resistors, capacitors, inductors, diodes, LEDs, batteries, and more
- Filter by value and package before you place a single part
- Keep summoning the same part, or switch and stay in flow
A workspace that adapts to you
Unmild Designer is designed to stay out of the way. Make panels float or dock, tune zoom and pan behavior, point zoom to the cursor, save navigation presets, and remap command keys.
- Customize zoom animation, zoom, horizontal and vertical pan, and hand-tool sensitivity
- Save navigation presets, retain custom colors, and restore the workspace you prefer
Release manufacturing data with confidence
Generate manufacturing artwork, drill data, bill of materials, placement information, stackup, review drawings, release notes, and a fabrication manifest together—built for a clean handoff from design to production.

Unmild Designer connects physical design with embedded firmware. Lay out the board, write C/C++ in Mool, program the microcontroller, watch the behavior, then release the complete design package. Discover the platform →
Questions people ask first
What is Unmild Designer?
A professional Windows electronics platform for PCB layout, embedded firmware, microcontroller behavior, 3D verification, analysis, and manufacturing release.
What file format does it use?
Projects are saved as .tamas files inside a project folder. Exporting adds a build folder alongside it holding the fabrication output.
What does Run actually simulate?
Run is the live board-behavior environment. It shows component state, readings, and issues in the context of the PCB, while Mool lets embedded C/C++ code program the microcontroller that drives the design.
What do I get when I export?
One export creates a complete release package: manufacturing artwork, drill data, bill of materials, placement information, stackup, review documentation, and fabrication information.
Is Unmild Designer free?
It is available through the Microsoft Store. View Unmild Designer on Microsoft Store.
