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.
MYD-SAMA5D3X boards specifications:
- Processor – Atmel SAMA5D31, SAMA5D32, SAMA5D34 or SAMA5D35 Cortex A5 up to 536MHz with 128KB of SRAM and 160KB of ROM
- System Memory – 512MB DDR2 SDRAM
- Storage – 256MB NAND Flash, 4MB Data Flash, 16MB Nor Flash, one MMC/SD card slot, and one microSD card slot
- Peripheral Interfaces
- Serial ports
- 1 x 3-line RS232 Debug serial port (DB-9)
- 1 x 5-line RS232 serial port (UART1, DB-9)
- 1 x RS485 serial port (UART2, 10-pin 3.5mm pitch terminal block connector)
- USB – 2 x High speed USB HOST, 1x Mini USB OTG
- Ethernet
- ETH1 – 10/100Mbps for SAMA5D31/35
- ETH0 – 10/100/1000Mbps for SAMA5D33/34/35
- 2 x CAN interfaces (only for SAMA5D34/35)
- 1 x HDMI interface (driver not available yet)
- 1 x Camera interface (driver not available yet)
- 1 x RJ11 Telephone interface (driver not available yet)
- Audio input and output ports
- 1 x LCD interface – Supports 24-bit true color TFT LCD, resolution up to 2048 x 2048 pixels (Not supported on SAMA5D35)
- 1 x 4-wire touch screen interface
- 1 x 20-pin standard JTAG interface
- 1 x Reset button, 1 x Wakeup button and 2 x User buttons
- 2 x Power indicators (Red, one on base board and one on CPU module)
- 1 x User LED (Blue on CPU module)
- 2 x expansion interfaces (J2, J3 and J4) with access to 2x SPI, 2x I2C, 1x PWM, 4x ADC, 41x GPIOs (some are multi-plexed)
- Serial ports
- Dimensions
- Base board – 154mm x 110mm (4-layer PCB)
- CPU Module – 45mm x 67.6mm (8-layer PCB)
- Power supply – 5V/2A
- Operating temperature range – 0~70 degrees Celsius (commercial grade) and -40~85 degrees Celsius (industrial grade)
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).
