Description

CpuArm01b is processor board of control system equipped with processor Atmel ARM9 working at 180 MHz and SDRAM 32 MB memory. Software equipment can be installed in embedded FLASH memory or removable MicroSD card.

Processor board is also equipped with battery-backed SRAM 512 kB, Watchdog, electrically isolated CAN bus, four RS232 interfaces and XBus interface for connecting extension boards.

The user program is loaded into the FLASH memory of the processor unit via RS232 serial line using built-in bootloader, or it can be stored on a MicroSD card (Linux).
