Think beyond the canvas
A bench for the next decision.
Explore schematic views, circuit analysis and design checks alongside the layout. Keep the questions close to the work.
Schematic & ERCDC / AC / transient analysisPCB checks
A place for
the whole board.
Turn a circuit idea into a board you can explore. Design the layout, program supported microcontrollers with Mool, follow the behavior in Live 3D, and prepare your manufacturing files—all in one Windows workspace.

Inside Designer / Live 3DTwo boards. One project.
01 / The workspace
Keep your idea.
And everything it connects.
Move between copper, code and circuit behavior without losing sight of the board you’re making.
Mool / Where behavior begins
Give the circuit
something to do.
Write C/Arduino-style programs for supported ESP32 and STM32 parts. Press Program, then watch inputs, outputs and the connected circuit respond.
- GPIO, PWM, timers and wired UART behavior
- Programs and editor drafts saved with your board
- Built-in examples to start from
Live 3D / More than a still view
See the shape.
Follow the behavior.
Review the board in three dimensions while Run brings supported components to life. Follow LEDs, motors, controls and electrical readings in context.
- Physical layout and live component state
- Interactive buttons and controls
- Readings and issues alongside the design
Board layout / Direct by design
From a blank board
to connected ideas.
Find parts with Saad, connect them with Setu, and shape the layout on a precise canvas. Keep multiple boards together when your idea needs more than one.
- Search parts by name, value or package
- Place, route, move, rotate and duplicate
- Grid snap, layers and board outlines
Personal workspace / Your rhythm
A familiar place.
On your terms.
Float or dock panels. Tune colors, shortcuts, zoom and pan. Save the working environment that feels natural to you and return to it next time.
- Configurable colors and tool shortcuts
- Navigation sensitivity and presets
- Flexible panels and local preferences
Keep what you make
Your project. In your folder.
Save the board and its Mool programs in a .tamas project. When it’s time to hand over the design, export a clearly organized build folder.
Local project filesSaved programsManufacturing exports
A closer look / The capabilities
Every part of the process.
Room to go further.
From finding the right component to seeing a program change the circuit, Designer keeps the practical details within reach.
01 / Mool · Code meets circuit
Write the response.
Watch the result.
A button press. A changing sensor input. An LED that follows your program. Mool connects supported C/Arduino-style code to the electrical behavior of ESP32 and STM32 models, so you can explore what your circuit does while you design it.
Start from a control example or write your own logic. Select the microcontroller, press Program and use Run to follow the response. Your programmed source and editor drafts stay with the board, ready for the next session.
- React to the circuit
- Read digital and analog inputs, drive GPIO and shape output with PWM.
- Coordinate the behavior
- Explore interrupts, supported timer callbacks and wired UART communication between parts.
- Start with something useful
- Try examples for temperature control, sensor processing, pulse handling and feedback control.
Run supported sketches in the workspace without installing an external compiler.
02 / Live 3D · A working view
A board you can see.
A response you can follow.
Bring the physical arrangement and circuit behavior into the same view. Inspect component placement, see supported LEDs respond, watch motors turn and interact with controls while the board is running.
Keep electrical readings and reported issues close to the design. When an input changes, you can follow its effect across the circuit instead of interpreting the program and layout in isolation.
- Interact with the idea
- Use momentary and latching controls to explore how the circuit responds.
- See the complete arrangement
- Review multiple boards in the same project, including designs with a separate controller and receiver.
- Connect the visual to the electrical
- Follow component state, readings and Problems feedback alongside the 3D view.
Explore behavior for supported component models throughout the design process.
03 / Layout · From part to placement
Stay with the idea.
Keep the tools close.
Saad brings the parts library to your canvas. Search by part, value or package, choose a component and place it where the design needs it. The library spans everyday passives, connectors, sensors, power components and microcontrollers.
Use Setu to draw connections, shape the board outline and refine the arrangement with direct selection tools. Move, rotate, duplicate and align your work with grid snapping, then keep related boards together in one project.
- Find and place
- Move from component search to the board without breaking the flow of layout.
- Refine with control
- Use editable traces, board shapes, layers and familiar canvas navigation to develop the design.
- Think in complete projects
- Arrange multiple boards together when one circuit is part of a larger system.
04 / Analysis & review
Ask better questions.
Make informed changes.
Move between schematic views, electrical-rule checks and board checks as the design develops. Explore DC, AC and transient RC analysis, or use the impedance calculator to investigate a design choice. These tools give you more context for the next revision.
- Schematic labels and named nets
- Electrical and PCB design checks
- DC, AC and transient RC analysis
- Microstrip and differential impedance calculations
05 / A workspace of your own
Your tools.
Your working rhythm.
Bring the panels you need into view and give the canvas the space it deserves. Float or dock panels, change colors, remap tool shortcuts and tune how zoom and pan respond. Saved local preferences make it easy to return to a familiar working environment.
- Floating and docked panels
- Custom colors and command keys
- Zoom, pan and navigation sensitivity
- Saved navigation presets
06 / Export & ownership
Keep the source.
Prepare the handoff.
Your editable design and Mool programs stay in the local .tamas project. Export creates a dedicated build folder with manufacturing artwork, drill data, assembly information and review material, making the next handoff easier to organize.
- Gerber X2 and Excellon output
- Bill of materials and pick-and-place files
- Review drawings and release information
- Local files you can back up and share
02 / How it connects
One project.
A connected way to work.
The layout gives the circuit its shape. Mool gives supported parts their behavior. Review and export bring that work into view.

04 / Good to know
A few useful
answers.
What can I do in Unmild Designer?
Design PCB layouts, arrange multiple boards, write supported microcontroller programs in Mool, explore behavior in Live 3D, review design checks and export manufacturing files. It’s one desktop workspace for the board and what it does.
How does Mool work?
Mool runs a supported C/Arduino-style subset for ESP32 and STM32 models against the connected circuit. Choose a part, write or load an example and press Program. Programs and drafts are saved with the board. Running a sketch in Mool does not require an external compiler.
What does Live 3D show?
The board and its placed components in three dimensions, with live behavior for supported parts during Run. See LEDs respond, motors turn and controls affect the circuit while following readings and reported issues.
Can I use Designer offline?
Core design, local project saving, Mool and exports work on your computer without a Designer account or AI API key. Downloading the app, Store services, external links and contacting support use the internet.
Where are my projects and exports?
Your project lives in the folder you select. The editable board uses the .tamas format, and File → Export PCB package writes output to a build folder within the project. Keep the project folder backed up.
Can I change the workspace?
Yes. Customize colors, tool shortcuts, zoom and pan behavior, and arrange floating or docked panels. Designer saves your local preferences for the next session.
Where can I get it, and what does it cost?
Visit Unmild Designer on the Microsoft Store for current pricing, availability and installation details. For a product or purchase question, contact UNMILD.
How is Designer related to UNMILD?
Designer is UNMILD’s dedicated electronics design product. It has its own workspace and purpose, alongside the other tools at unmild.store.
