Arbor has launched two COMs based on Intel’s quad- and dual-core Atom E3800 SoCs, and built on 70 x 70mm Qseven and 84 x 55mm COM Express Mini form factors.

Arbor Technology has begun shipping the Qseven form-factor EmQ-i2301 computer-on-module, but made no mention of a ship date for the COM Express Mini Type 10 based EmNANO-i2300. Each is offered with a variety of Intel Atom E3800 system-on-chips. The company touts the 22nm-fabricated SoCs for their “ample L2 cache, which can be shared by multiple cores, and a much faster Intel HD graphics unit.”

Among other benefits, the CPU cores are faster than previous Atoms, and offer much lower power consumption. Neither module supports the power-stingy, single-core Atom E3815, but both provide a range of offerings from the dual-core Atom E3825 (1.33GHz clock, 6 Watt TDP) to the quad-core Atom E3845 (1.91GHz/10W TDP).

As usual, Arbor does not list OS support, but the company typically supports Linux on its products, and Linux should run just fine. Other x86-based COMs from Arbor include the COM Express Type 6 Basic form-factor EmETXe-i87M0, which runs on Intel Core 4th Gen “Haswell” processors, and the COM Express Type 10 Mini styled EmNANO-a56M0, which features the AMD G-Series SoC.

 
EmQ-i2301

The immediately available EmQ-i2301 Qseven module supports multiple Atom processor E3800 SoCs, as well as the closely related Intel Celeron N2930. The modules are fitted with ceramic capacitors, making them suitable for industrial mobile applications in harsh environments, says Arbor.

The EmQ-i2301 joins a growing list of Qseven form-factor COMs that offer Atom E3800 chips, including Congatec’s COM Express Mini Type 10 Conga-MA3, and COMs from MSC and Seco, both of which are dubbed the Q7-BT.

The EmQ-i2301 is a much simpler affair than the Congatec, MSC, and Seco COMs. The standard model ships with just 2GB of soldered LVDDR3 RAM, with the maximum 4GB allotment requiring a special order. An optional soldered 16GB of eMMC flash is also a build-to-order option.

Display features are competitive, with a DDI port providing HDMI or DisplayPort screens, the latter running at up to 2560 x 1600 pixels. There’s also dual display support with DisplayPort and the available 24-bit LVDS interface. An Intel i210IT gigabit Ethernet controller is also available.

The EmQ-i2301 is notable for being one of the few Atom E3800-based COMs we’ve seen that does not support USB 3.0. You get eight USB 2.0 connections via the Qseven-standard 314-pin MXM connector, as well as a pair of SATA 2.0 interfaces, an HD audio interface, and three PCI-Express x1 links. The press release notes the availability of MIPI camera, I2C bus, and LPC bus interfaces, but these are not listed in the data sheet.

Other touted features include Intel AES-NI encryption support. The 70 x 70mm module is also said to support temperatures ranging from -20 to 70°C.

Specifications listed for the EmQ-i2301 include:

  • Processor — Intel Atom “Bay Trail” with Intel HD Graphics Gen. 7:

  • Power — 5V; 0.93A@+12V typical consumption with E3825
  • Operating temperature — -20 to 70°C
  • Dimensions — 70 x 70mm; Qseven form factor

 
EmNANO-i2300

The EmNANO-i2300 uses the 84 x 55mm COM Express Mini Type 10 form-factor. It supports four different Intel Atom E3800 processors. Which of these are standard vs. build-to-order (BTO) options varies depending on the PR and the datasheet.

The announcement lists the dual-core E3825 and E3827 as the standard CPUs, with the dual-core E3826 and quad-core E3825 indicated as BTO, whereas the data sheet says the standard models are the E3825 and E3845. (We don’t mean to single out Arbor here, but it’s truly amazing to us how often press releases differ from datasheets, which sometimes differ from the product pages. Yo, marketing and engineering folk: Use your words!)

No matter what the processor, you get 2GB soldered DDR3L RAM, with 4GB optional. There’s no NAND flash onboard. Display offerings are the same as with the EmQ-i2301 Qseven modules, as are the additional SDIO and SATA interfaces and gigabit Ethernet controller.

The EmNANO-i2300 supports one USB 3.0 port in addition to eight USB 2.0 ports. There’s also a serial port, HD audio, as well as LPC, SPI, and I2C connections, says Arbor. Once again, three PCIe x1 interfaces are said to be available. You get a choice of 12V or optional 5V power supplies, and the operating range is once again listed at -20 to 70°C.

Specifications listed for the EmNANO-i2300 include:

  • Processor — Intel Atom E3800 (Bay Trail-I); Intel HD Graphics (some may be BTO):
