OpenBoardView is the free, open-source boardview viewer most technicians start with. It runs on Windows, Linux and macOS, opens the most common laptop boardview formats and does the essential jobs — find a part, highlight a net, flip the board — quickly and without fuss. This guide gets you from download to a useful setup.

Where to get it

OpenBoardView is developed in the open on GitHub under the project name OpenBoardView. Download releases from the project's official release page, not from file-sharing sites or archives bundled with boardviews: viewer executables passed around in repair archives are a common way to spread malware.

Releases are provided for Windows and macOS, and the source builds on Linux; several Linux distributions also package it. If your platform is not covered by a ready-made build, the project's documentation explains how to compile it. Notes for non-Windows systems are in Using Boardview Software on Mac and Linux.

Installing on Windows

  1. Download the latest release for Windows from the official release page.
  2. Run the installer or unpack the archive to a folder of your choice, depending on which package you downloaded.
  3. Start the program once to confirm it opens. It uses OpenGL for drawing, so very old graphics drivers occasionally cause a blank window — updating the graphics driver usually fixes it.
  4. Optionally associate common boardview extensions (.brd, .bdv, .fz) with OpenBoardView so double-clicking a file opens it.

Opening your first file

  1. Unpack the boardview from its archive into a working folder. Keep any companion files of a multi-file format (such as .ASC sets) together.
  2. Open it from the File menu, or drag the file onto the window.
  3. The board outline appears with every part drawn as an outline. If you see nothing, zoom out — some files place the board far from the origin.

If the file does not open at all, it may be a format or variant OpenBoardView does not support. The format guide Boardview File Formats Compared: BRD, BDV, FZ, CAD, TVW, ASC explains which formats work where.

Getting around the board

The exact shortcuts depend on the version; the View menu and the help screen list them for yours. The core actions are:

  • Zoom with the mouse wheel, centred on the pointer.
  • Pan by dragging with the mouse.
  • Flip between the top and bottom sides. Do this every time you turn the physical board over, so the screen matches what you see under the microscope.
  • Rotate the view in steps so the board on screen has the same orientation as the board on your bench.
  • Reset the view to fit the whole board when you get lost.

Spend a minute matching the on-screen orientation to the real board before you start a job. It prevents probing the mirror-image position of the part you meant.

Finding parts and nets

Search is the feature you will use most:

  1. Open the search box (usually from the menu or with the standard find shortcut).
  2. Type a reference designator — PU301, PC113, U23 — to jump to a part.
  3. Or type a net name — +3VALW, EC_ON — to highlight every pin on that net.
  4. Partial names work in most versions, which helps when you only remember part of a net name.

Clicking a part shows its details: designator, pin count and, for each pin, the net it belongs to. Clicking a pin highlights its whole net across both sides of the board. Faster search techniques are covered in Finding Component Locations Fast with Boardview Search.

Reading what you see

  • Part outlines show the footprint size. Large rectangles near the CPU are inductors and power MOSFETs; tiny outlines are 0402 or 0201 passives.
  • Pin 1 is marked on ICs. Use it to orient yourself before probing chip pins.
  • Highlighted pins show every place a net reaches, including the bottom side when you flip.
  • Test points and vias appear as small round pads on many formats — the safest places to probe.
  • Values appear only if the file contains them. Many do not; take values from the schematic.

Settings worth changing

OpenBoardView keeps its settings in a configuration file and exposes many of them in a preferences window. Worth adjusting:

  • Colours and contrast. A dark background with bright part outlines is easier on the eyes during long sessions.
  • Annotation and pin display. Show pin numbers or net names on hover if your version supports it.
  • Font and UI scale. On high-resolution screens, increase the interface scale so text is readable.
  • Format-specific options. Some formats, notably some .FZ files, need extra settings such as a decoding key. These are not shipped with the program.

A first exercise

Pick any board you have on the bench with its boardview:

  1. Find the DC jack or USB-C connector and highlight the adapter input net.
  2. Follow the highlight to the input protection parts and note their designators.
  3. Search the always-on 3.3 V rail name from the schematic and look at how many parts share it.
  4. Flip the board and see which of those parts are on the bottom.
  5. Find a test point or large capacitor on that rail and locate it on the real board.

After this, you know the viewer well enough for real repairs. The next step is combining it with the schematic, as in How to Use a Schematic and a Boardview Together.

Keeping it fast and safe

A few habits make the viewer more pleasant to live with:

  • Keep boardviews out of the program folder. Store them in a separate library folder organised by board code, so updating the viewer never touches your files.
  • Update from the official page only. New releases add formats and fix crashes, but builds from unofficial archives may be modified.
  • Open archives with care. Boardview collections often arrive as large archives from unknown sources. Unpack them with an up-to-date archiver and scan them before opening anything that is not a boardview.
  • Use a second monitor for the schematic. OpenBoardView has no PDF integration, so a second screen for the schematic avoids constant window switching.

FAQ

Is OpenBoardView really free?

Yes. It is open-source software. Download it from the official project page to make sure you get an unmodified build.

Does OpenBoardView open schematics too?

No. It opens boardview files. Keep the PDF schematic open in a separate viewer. Some commercial viewers can link the two; see FlexBV vs OpenBoardView vs Other Viewers: Which to Use for the differences.

Why do some boards look upside down?

Boardview files store coordinates in the layout's own orientation. Rotate and flip the view until it matches the physical board; the setting stays for the session.

Can OpenBoardView show diode-mode readings?

When the file contains them, many versions can display them. Most files do not include readings, so this depends on the source of the boardview.

Bottom line

Install OpenBoardView from the official source, learn search, flip and net highlighting, and match the on-screen orientation to your board before every job. That covers most day-to-day boardview work, and it costs nothing.
