What Is the PPM-C407-3825-4-0-ST?
The PPM-C407-3825-4-0-ST is a part number from WinSystems' PPM-C407 family of fanless PC/104-Plus single board computers (SBCs). In WinSystems' ordering scheme, the digits decode as follows: 3825 identifies the Intel Atom® E3825 dual-core processor running at 1.33 GHz, 4 indicates the board is populated with 4 GB of soldered DDR3 memory, 0 denotes a base configuration option, and ST refers to the standard operating temperature version. The PPM-C407 is built around Intel's Atom® E3800 processor family, which spans the single-core E3815 (1.46 GHz), the dual-core E3825 (1.33 GHz) and the quad-core E3845 (1.91 GHz).
Key Specifications and Technical Details
The board is designed for embedded and industrial duty, with soldered-down RAM for shock and vibration resistance and an operating temperature range of -40°C to +85°C. It offers Intel Gen 7 graphics with up to two simultaneous displays (VGA up to 2560×1536, LVDS 18/24 bpp and DisplayPort 1.1), a SATA 2.0 channel plus an mSATA socket shared with miniPCIe, 24 bidirectional GPIO lines with event sense, four serial ports (two configurable as RS-232/422/485 and two RS-232), four USB 2.0 ports with surge suppression, and an adjustable watchdog timer from 3 to 300 seconds. Expansion is provided through the PC/104 and PC/104-Plus buses plus Mini PCIe, and the board runs on a single +5V DC supply. It is RoHS-compliant and measures 4.55 × 4.02 × 0.513 inches (115.57 × 102.11 × 13.03 mm). WinSystems documents support for Linux, Windows (including Windows 7, 8, 10 and CE) and DOS environments.

Use Cases and Applications
PC/104-Plus SBCs like the PPM-C407 are typically deployed where a stackable, rugged computing core is needed inside a larger enclosure: industrial automation controllers, energy and utility monitoring equipment, transportation systems, medical and laboratory instruments, and legacy industrial machinery that relies on ISA-era expansion. The wide temperature range, fanless operation and soldered memory make this class of board suitable for dusty, vibrating or temperature-extreme environments where a standard desktop or mini PC would not survive. Typical deployments pair the board with a custom carrier or I/O stack and run a lightweight Linux or legacy Windows/DOS image.
Choosing an Industrial Computing Platform Today
When specifying a new embedded system, it helps to compare the PC/104-Plus SBC approach with modern integrated industrial computers. A board-level SBC gives maximum flexibility for custom carriers and legacy bus expansion, but it requires enclosure design, power engineering and integration work. A finished industrial mini PC or fanless industrial computer, by contrast, arrives ready to deploy with a validated thermal design, standard I/O and a supported operating system image — often at a lower total cost once integration labour is counted. If your application still depends on PC/104 or ISA expansion, a board-level module remains the practical route; if you are building new equipment, a compact fanless system is usually faster to certify and maintain.
| Consideration | PC/104-Plus SBC | Fanless Industrial Mini PC |
|---|---|---|
| Integration effort | High (carrier, enclosure, power) | Low (ready to deploy) |
| Expansion | PC/104, PC/104-Plus, Mini PCIe | Standard USB, serial, HDMI, Ethernet |
| Thermal design | System integrator's responsibility | Validated by manufacturer |
| OS support | Manual image and driver setup | Pre-installed and tested |
| Best fit | Legacy bus-dependent equipment | New industrial and commercial builds |
