Pico-ITX SBC runs Android on TI Sitara SoC
Sep 19, 2013 — by Eric Brown 7,076 viewsKontron announced a Linux- and Android-ready Pico-ITX single board computer with extended temperature support, built around a Texas Instruments Sitara AM3874 system-on-chip. The KTAM3874/pITX provides up to 2GB RAM and 16GB flash, supports HDMI/LVDS dual displays, runs on less than 5 Watts, and offers I/O including Ethernet, USB 2.0, serial, CAN, and SATA, plus mini-PCIe and microSD expansion.
The KTAM3874/pITX is the first Kontron Pico-ITX SBC designed to operate from -40 to 85°C, says the company. Available with a minimum of seven years long-term availability, the 100 x 72mm board supports a wide range of applications ranging from industrial use to digital signage. Targeted applications are said to include autonomous battery- or solar-powered outdoor systems, or mobile or stationary dual-display computers including Box PCs, HMIs, and thin clients.

The board’s Texas Instruments Sitara AM3874 SoC is equipped with a single ARM Cortex-A8 core clocked at up to 800MHz. It’s the only 3D-accelerated model of the three Sitara AM387x SoCs TI introduced in 2011. Video acceleration is available, but it lacks the TI C64x+ DSP supplied by the pin-compatible, HD-video ready DM8148/8168 SOCs.

In April, Kontron announced a SMARC form-factor computer-on-module called the SMARC-sA3874i, which is based on the same AM3874 SoC and provides a similar feature set to the KTAM3874/pITX.

The KTAM3874/pITX is equipped with 1GB of DDR3, with an option for 2GB, and it ships with 4GB of eMMC NAND flash, with an option for 16GB. A microSD slot is available, along with a SATA interface. There’s also an mSATA interface on a mini-PCI-Express connector, and a separate Mini-PCIe-based SIM card slot.
The board supports up to two independent displays via 24-bit dual channel LVDS and HDMI 1.3a interfaces, with the latter capable of supporting 1080p HD video, says Kontron. Analog audio I/O is available, along with a separate, 1W loudspeaker port “for making acoustic acknowledgement or for speech output,” says the company.
Dual 10/100 Ethernet ports are supported with an optional switch. Along with the HDMI port and two of the five available USB 2.0 ports, these are the only real-world coastline ports on the board. Of the three other USB ports, one is a client port, and another is available on a mini-PCIe connector. Other I/O includes dual CAN bus interfaces, dual RS232, and a single RS435, as well as 26x GPIOs, I2C, UART, and SP outputs.
The KTAM3874/pITX ships with a Linux BSP, but is also said to support Android and Windows WEC7. Kontron’s in-house services include individual driver implementations and configuration-specific images.

The Kontron KTAM3874/pITX is available now at an unstated price. More information may be found at Kontron’s KTAM3874/pITX product page.
It all depends on not price but Linux kernel support. Similar to RaspberryPi but killing it with its addons – speaker, usb, mpcie, battery, sim.
Once its supported by mainline kernel – it’s the winner of mini ARM computers.
