APF28




the APF28: a perfect processor board for low cost embedded Linux systems

Description

The APF28 is a very small size processor board without FPGA. This configuration allows Armadeus systems to propose a highly competitive price & performance product.(Click here to get the price list)

Fitted with a 454MHz i.MX28x (ARM9) processor, 128 MB RAM DDR2, 256 MB of FLASH SLC NAND, one or two 10/100Mbits Ethernet ports, 2 CAN, one USB 2.0 High Speed and one USB OTG, it is easily integrated into an embedded system thanks notably to its regulators and transceivers (USB & Ethernet).

Note : no external debugger (BDI, JTAG) is required. When it is used with the APF28_Dev board, A simple USB wire is enough for "low-cost" development. A Linux debugger is available (GDB).



Armadeus systems provides a complete Linux distribution (Click here for more details). All the development tools are already included.
