Linux-friendly 3.5-inch SBC offers dual GbE

May 28, 2014 — by Eric Brown — 1,791 views

Axiomtek’s CAPA112 SBC uses an AMD G-Series APU and offers dual display support, two GbE, six USB, and four COM ports, and PC/104 and Mini-PCIe expansion.

The CAPA112 is designed for fanless, embedded applications that need rich graphics, legacy ISA support, and a wide operating temperature range, says Axiomtek. Applications are said to include medical imaging, digital signage, kiosks/POI, thin clients, and gaming machines. The device can withstand temperatures ranging from -40 to 70°C.

This 3.5-inch single board computer runs on an AMD Embedded G-Series APU, with either a 1GHz, dual core T40E or a 615MHz, single-core T16R. In either case, it offers built in Radeon HD 6250 graphics, and is paired with the A55E FCH controller chipset. Axiomtek recently released a PICO121 Pico-ITX board featuring the full SoC version of the G-Series, which has an integrated controller. Other recent 3.5-inch SBCs from Axiomtek include its Atom E3800-based CAPA841.

The CAPA112 can be equipped with up to 4GB of DDR3 RAM, and features a CFast slot and a SATA 600 interface for storage. The SBC is notable for offering two standard gigabit Ethernet ports, as well as a PC/104 module location for 16-bit ISA-bus expansion. There’s also SMBus connectivity and an LPT Parallel interface, and for more up-to-date expansion, a Mini-PCI Express slot with mSATA support.
