Chapter 2 Product Overview

Product Description

The MightyBoard 821 is an exceptionally high integration, high performance, rugged, and high quality single-board computer, which contains all the component subsystems of an ATX motherboard plus a single PCI expansion slot. Based on Intel processors (Pentium M or Celeron M), the MightyBoard 821 gives designers a complete, high performance embedded processor based on the Mini-ITX form factor.

Each MightyBoard 821 incorporates an Intel 915GM chipset (82915GM + 82801FBM) and provides four serial ports, an EPP/ECP parallel port, six USB 2.0 ports, PS/2 keyboard and mouse interfaces, and one Ultra DMA 33/66/100 IDE controller supporting two IDE drives, two independent 10/100BaseTX and 1000BaseT Ethernet interfaces, and an audio AC'97 CODEC on the board. The MightyBoard 821 also supports up to 2GB of SDRAM in a single 184-pin DDR DIMM slot, and an AGP4x equivalent graphics controller, which provides CRT and LVDS flat panel video interfaces for the most popular LCD panels.

The MightyBoard 821 can be expanded through a single x16 PCI Express (PCIe) bus slot for additional system functions. This PCIe bus operates at clock speeds up to 100MHz.

Among the many embedded-PC enhancements on the MightyBoard 821 that ensure embedded system operation and application versatility are a watchdog timer, serial console support, battery-free boot, and BIOS extensions for OEM boot customization.

The MightyBoard 821 is particularly well suited to either embedded or portable applications and meets the size, power consumption, temperature range, quality, and reliability demands of embedded system applications. The MightyBoard 821 requires an ATX power supply or a single +5V power supply.
