3.1 PCM-7230 Mainboard for SPC-57
The Engine of SPC-57 is constructed by the combination of 2 PCBA – one
mainboard and one I/O board. The mainboard is slightly modified based on
Advnatech standard product PCM-7230 to fulfill SPC-57 specification. In this manual,
we will still use PCM-7230 to mean the mainboard although it is slightly different
from our standard product. The PCM-7230 SBC for SPC-57 is a 3.5” (145mm x 102
mm x 21.1mm) single board computer with the Intel
®
PXA255 processor running at
200 MHz. The milli-watt power consumption by its kernel makes the PCM-7230
suitable for power conscious applications.
