WinSystems unveiled a Linux-ready, 3.5-inch SBC35-CC405 board with an Atom E3800 SoC, plus industrial temperature support and mini-PCIe and “IO60” expansion.
The SBC35-CC405 single board computer is consistent with a recent trend of rapidly-reconfigurable SBCs that use computer-on-modules (COMs) as their removable embedded engines. The COM here is a modified version of the Portwell PCOM-B632VG, a 95 x 95mm COM Express Type 6 “Compact” module announced in October featuring the Intel Atom E3800.

The SBC35-CC405 also represents the trend toward offering more flexible I/O expansion options. In this case WinSystems is supplying both a mini-PCIe socket, as well as the company’s rugged, stackable, 60-pin “IO60” expansion bus. The 3.5-inch (actually 5.75 x 4.0 inch) SBC is designed for rugged embedded applications requiring extended temperature operation (it supports -40 to 85°C) , long-term availability, and a wide variety of I/O expansion options, says the company.
The SBC35-CC405 offers different SKUs based on slightly different PCOM-B632VG COMs. These include a single-core, 1.46GHz Atom E3815 (4.5W TDP), a dual-core, 1.75GHz Atom E3827 (8W TDP), or the quad-core, 1.91GHz Atom E3845 (10W TDP).

All three SBC versions ship with 2, 4, or 8 GB of DDR3L SDRAM. All other features are the same, including the CFast and mSATA sockets (the latter via Mini-PCI Express), and an onboard SATA 2.0 interface. Dual displays are supported with the available DisplayPort, VGA, and LVDS connections.
Dual gigabit Ethernet ports with IEEE 1588 time-stamping are on the SBC’s coastline, along with a USB 3.0 port, three USB 2.0 ports, and audio I/O. The board ships with dual RS-232/422/485 ports featuring clock options up to 20Mbps in the RS-422/485 mode and up to 1Mbps in the RS-232 mode, says the company.
The SBC35-CC405 includes dual Mini-PCIe connectors and one proprietary IO60 connector for expansion. Both Mini-PCIe connectors support half-length and full-length cards with screw-down mounting for improved shock and vibration durability, says WinSystems. One Mini-PCIe connector supports bootable mSATA solid state drives while the other supports USB.
Multi-architecture IO60 expansion connector
The IO60 expansion connector is a WinSystems creation intended to provide stackable, PC/104-like connectivity for both ARM and x86 embedded projects. It features a 60-pin, “hermaphroditic, self-mating” stacking connector suitable for rugged conditions, says the company. The company quietly debuted IO60 on its 3.5-inch form factor SBC35-C398 ARM SBC last April, but recently has started promoting it more proactively.

On the SBC35-CC405, the IO60 connector provides access to I2C, SPI, PWM, and UART signals for sensors, data acquisition, and other low speed I/O applications. In order to keep the interface simple, WinSystems decided not to support features such as USB or Ethernet directly on IO60, but the expansion bus does include signals for SMBus, PCIe x1, and eight GPIOs. The connector also provides +5V and +3.3V power, plus six undefined pins for future expansion.

The IO60 spec features a Samtec LSEM Series board-to-board connector with a double row of 30 gold-plated contacts per row set on a 0.8mm pitch. The 6mm high connector can support PCIe speeds up to 9.5 Gbyte/s, enabling serial buses with different speeds to be mixed on the same connector.

In addition to the IO60 expansion bus connector, WinSystems has defined a 72 x 50mm expansion module form-factor, featuring two threaded spacer holes for board separation and rigidity. These dimensions are said to be small enough for use on 100 x 72mm Pico-ITX boards, as well as on larger form factors like EPIC, EBX, and 3.5-inch boards. WinSystems supplies off-the-shelf IO60 modules and custom designed modules for OEM applications. These include a DIO module, as well as a GPS/GNSS receiver module (see images above). The company also told LinuxGizmos that IO60 specs are available for use by third-party board makers.
The SBC35-CC405 offers a wide input power range of 10-50V DC, and supports industrial temperatures of -40 to 85°C. The PCB is mounted sandwich style on a low-profile thermal solution that offers further protection while also providing a heatsink and four-point mounting.
The board ships with Linux and Windows7/8 drivers, and supports other x86 operating systems, all of which can be booted via CFast, mSATA, SATA, or USB. WinSystems supplies enclosures, power supplies, and configuration services for turn-key OEM embedded computing platforms.
