I am blind, I like this beautiful coastal city in Shenzhen, her young, energetic, open, not rotted, has born a lot of light-oriented technology companies, Mir Technology Hehe, is committed to the development of ARM platform. Embedding Software hardware, after the birth of the birth, it is always unswervingly providing a hardware and software development tool, an embedded system complete solution, etc. Recently, Mil Technology is more frequent, launched a lot of developments, such as MYD-SAM9X5 development boards for M2M applications, such as M2M applications. In the wave of the M2M trend, its "upgrade board" MYD-SAMA5D31 is also born.
MYD-SAMA5D31 out of the box
The first feeling of MYD-SAMA5D31 is that Mil Technology is very hard, and its rich accessories are a big feature compared to the general development board.

The MYD-SAMA5D31 development board includes a bottom plate MYB-SAMA5D31 with the SO-DIMM interface holder and a core board myc-sama5d31, and the bottom plate and the core plate can communicate with other series of MYD-SAMA5D3X.
MYD-SAMA5D31 Main parameters:
Processor ATSAMA5D31 / 33/34/35 (Support for 4 core boards), ARM® Cortex-A5 processor, 536MHz running frequency
Memory 256MB NAND-FLASH, 512MB DDR2 SDRAM
Audio interface all the way audio 3.5mm input interface, all the way two-channel audio 3.5mm output interface
LCD touch screen interface 24-bit true color resolution: 4.3 inch 480x272, up to 1280 x720
20-pin, 2.54mm standard JTAG interface
1 road MMC / SD card interface, 1 TF card interface
Serial port 1 road trial serial port DBGU (Debug Unit) 3 line, 1 way ordinary serial port UART1 5 line, 1 way RS485 interface
RS485 interface, shared with USART0, can pass through jumper switching interface
2 channels of CAN interface (SAMA5D31 / SAMA5D33 does not support)
2 high speed USB HOST interface, 1 way mini usb host / device interface
1 road 10 / 100MB / s Ethernet interface (SAMA5D33 / SAMA5D34 does not support)
1 power indicator
Core Board Myc-Sama5d31
The core board Myc-Sama5d31 is very simple, unscrewing two plastic screws, and the core plate can be removed by the light SO-DIMM card Switch.
As the name, the core board is the most important part of the entire board. Its embedded microprocessor unit is the latest MPU-SAMA5D31 provided by Atmel, based on the ARM® CortexTM-A5 kernel, can provide up to 536MHz at a power consumption of less than 200 mW (850DMIPS) handling capacity is a very cost-effective high-performance, low power platform.
