MYD-IMX283 Development Board

Description of product

MYC-IMX28X CPU Module | Freescale i.MX28, i.MX283, i.MX287, ARM9 Controller Board-Welcome to MYIR

Measuring only 62mm by 38mm, the MYC-IMX28X is a low-cost and high-performance ARM embedded controller board based on NXP i.MX28 family applications processor with ARM926EJ-S core and speeds of up to 454MHz. It integrates 128MB DDR2 SDRAM, 256MB Nand Flash, 128KB SPI Flash as well as one Ethernet PHY on board and has two 1.27mm pitch 80-pin SMT connectors to allow all the I/O signals brought in and out from the CPU Module for further expansion.


The MYC-IMX28X CPU Module is a ready-to-run system-on-module (SoM) which can be embedded into your next design for volume production or prototype. It can also come with MYIR own designed base board along with Linux 2.6.35 software packages, document and other necessary cable accessories to enable rapid development based on this Freescale i.MX28 starter kit MYD-IMX28X.
