VMIC VMIPC4-7301 Embedded Single Board Computer

Module Feature

VMIC VMIPC4-7301 Legend B is a compact low-power X86 embedded single board computer built around National Semiconductor Geode GX1 processor delivering Pentium MMX equivalent performance. Low power consumption eliminates requirement for active fan cooling. Integrated onboard peripherals including graphics controller, Ethernet interface, serial UART ports, IDE storage interface and keyboard/mouse controller. Flash BIOS supports in-field firmware upgrade. Rugged PCB construction with excellent shock and vibration tolerance, designed for space-constrained embedded control, data acquisition, test & measurement and aerospace applications.

Working principle

The Geode GX1 processor executes embedded operating system and user application code. System memory and onboard peripheral controllers are mapped into the CPU address space. Integrated graphics unit drives display output; Ethernet and serial controllers handle external communication. Flash memory stores BIOS firmware for system boot. Hardware watchdog timer automatically resets the board upon software lockup to improve system reliability.

Onboard components

National Semiconductor Geode GX1 CPU, onboard SDRAM, integrated graphics controller, Ethernet PHY chip, multi-channel UART, flash BIOS chip, watchdog timer circuit, front panel I/O connectors, status LED indicators.

LED indicators

Front panel LED indicators for power status, CPU heartbeat, Ethernet link and activity, system fault warning.

Hardware self-diagnosis

Visual inspection of PCB, front panel connectors and solder joints; power-on POST self-test; memory read/write cyclic test; Ethernet loopback verification; serial port communication test; BIOS and watchdog function validation.

Programming software

Supports VxWorks, Linux, Windows embedded OS; VMIC board configuration utility, diagnostic firmware and driver package.
