MYIR MYD-SAMA5D3X Development Boards Feature Atmel ARM Cortex-A5 SAMA5D3 Processors

MYIR Tech, a company based in Shenzhen, and ARM Connected Community Member, has recently made available MYD-SAMA5D3X boards powered by Atmel ATSAMA5D3 ARM Cortex-A5 embedded MPU. Like many development boards, thise are composed of a baseboard coupled by a 200-pin SO-DIMM computer-on-module (CoM) featuring one of the four Atmel SAMA5D3 processor: SAMA5D31, SAMA5D33, SAMA5D34 and SAMA5D35. The boards all feature 512MB DDR2 SDRAM, 256MB Nand Flash, 16MB Nor Flash and 4MB Data Flash on board. Typical applications developed with these boards include control panel/HMI, smart grid, medical and handheld terminals, outdoor GPS, DECT (digital enhanced cordless telecommunications) phones, and more.

The board is sold with a 5V/2A power adapter, an Ethernet cable, a USB Cable, a DB9 to DB9 serial cable, and a DVD with user manual, schematic in PDF format, datasheet, and software packages. The company can also separately provide a 4.3″ LCD with touch screen ($60), and a 7″ LCD with touch screen ($99). When Atmel announced SAMA5D3 eMPU at the beginning of the year, they delivered Linux 3.6.9 and promised Android 4.0.4 at a later date, and that’s exactly what you get with MYIR boards. According to the user’s manual, the source code is apparently available for all software component including the first stage bootloader, u-boot, the linux kernel, and all drivers.

The baseboards are available for $290, but you’ll need to add $100 to get one of the MYC-SAMA5D3X CPU modules, which adds up to $390 for a commercial grade system. For comparison, Atmel devkits cost between $445 (Atmel SAMA5D35-EK without LCD) to $595 (Other devkits with a 5″ WXGA display module).
