Axiomtek’s credit card-sized “CEM300” module runs Linux on Intel Braswell SoCs at 4-6W TDP and offers HD graphics, dual SATA III ports, and four PCIe lanes.
Like Axiomtek’s Atom E3800 “Bay Trail” based CEM846 computer-on-module, its new CEM300 supports Linux and Windows, and uses the 84 x 55mm COM Express Type 10 Mini form factor. The CEM300 advances to 14nm Intel Braswell SoCs, which offer much improved Intel HD Graphics Gen8, while reducing TDPs to a 4W to 6W range. Supported models include the quad-core 1.6GHz (2.4GHz burst) Pentium N3700, the quad-core Celeron N3160, and the dual-core Celeron N3060.
The CEM300 is designed for applications including industrial IoT automation controllers, medical imaging, and retail/POS/kiosk. The module offers 3.5Grms vibration resistance and supports temperatures of 0 to 60°C.

The CEM300 ships with 4GB or 8GB of DDR3L RAM, and offers dual SATA-600 interfaces and a GbE controller with Wake-on-LAN and PXE boot. For displays, you get a DDI port supporting HDMI/DVI/DisplayPort, and either an 18/24-bit, single channel LVDS or an optional embedded DisplayPort (eDP).
The module provides 2x USB 3.0 ports, 8x USB 2.0 ports, 4x DIO channels, and 2x serial TX/RX interfaces. You’ll also find LPC, SPI, SMBus, smart battery, and HD audio interfaces. Three PCie lanes are supported, or four if you’re not using the Gigabit Ethernet port. Options include a heatspreader and heatsink with fan.
The CEM300 supports wide-range 4.75V to 20V power n AT mode and adds +5VSB power in ATX mode. A watchdog and hardware monitoring are onboard, and you can also use Axiomtek’s AXView 2.0 intelligent remote management software.
The CEM300 is supported with a COM Express Type 10 CEB94008 carrier board. The 291 x 244mm board offers a -40º to 85ºC range, although that’s not going to help out much with this commercial temperature module.

The main coastline panel offers a VGA port, audio I/O, 2x GbE ports (one with WOL and PXE), 2x USB 3.0 port, and 2x USB 2.0 ports. Four more USB 2.0 ports are available internally, adding up to a total of 10 USB ports.
CEB94008 differs from most carriers in that it offers a bank of eight DB9 COM ports along the side of the board. Four are RS-232 ports, and there’s a pair each of RS-232/422/485 and TX/RX ports.
The CEB94008 is further equipped with a single SATA port, a CFast storage slot, and LVDS and DDI interfaces. You also get 2x PCIe x1 slots, a mini-PCIe slot, 8-channel DIO, and an SMBus connector. The board’s power supply was not disclosed, although the detail diagram shows ATX and DC connectors. The board also provides a 3V/195mAH Lithium battery.
