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.
