The MYD-IMX28X Development Board designed by MYIR is a cost-effective and power-efficient ARM Evaluation Kit (EVK) for NXP i.MX28 family of multimedia applications processors which has an ARM926EJ-S Core, with speed up to 454 MHz. The board can support running Linux operating systems, which allows developers to use it as an i.MX28 reference platform to quickly start their own design. The board takes full features of the i.MX28 ARM processor and has exposed a comprehensive set of peripherals and connectivity options to make the board suitable for smart gateways, human-machine interfaces (HMIs), handheld devices, scanners, portable medical, experimental education and more other industrial applications.



The MYD-IMX28X Development Board is using the MYC-IMX28X CPU module as the heart of the system which is an ARM9-based system-on-module (SOM) integrated with the i.MX28 processor, 128MB DDR2 SDRAM, 256MB Nand Flash and Ethernet PHY. It is connected to the base board through two 1.27mm pitch 80-pin connectors. The base board has extended many peripherals and interfaces through headers and connectors, featuring 1 x RS232, 1 x Debug, 2 x USB ports, up to 2 x Ethernet, 2 x CAN, 1 x RS485, TF, Audio, LCD, JTAG, etc.





MYIR offers the board with Freescale i.MX283 or i.MX287 ARM9 CPU by default; user can integrate a different MYC-IMX28X CPU module on the same base board, thus making two variants of i.MX28 evaluation boards. MYD-IMX283 Development Board – with MYC-IMX283 CPU Module for Freescale i.MX283 MYD-IMX287 Development Board – with MYC-IMX287 CPU Module for Freescale i.MX287

The MYD-IMX283 and MYD-IMX287 boards only have a few differences as described in below table: Model MYD-IMX283 MYD-IMX287 Processor i.MX283 i.MX287 CAN 0 2 Ethernet 1 2

The MYD-IMX28X board comes with Linux2.6.35 software packages, detailed documents, necessary cable accessories as well as optional 4.3- and 7-inch LCD (with resistive or capacitive touch screen), WiFi, GPS and GPRS modules to provide a complete Freescale i.MX28 starter kit and enable a quickly start of evaluation of i.MX28 family applications processors.
