1.1 Introduction
MIO-5251 is designed using MI/O Extension form factor (compact series, 146 x 102
mm) and powered by the latest generation of Intel
®
Celeron
®
J1900 and Atom™
E3825 processors which have low power features but also good performance com-
puting, especially for multimedia capabilities compared to earlier generations. Mean-
while, MIO-5251 offers flexible expansion possibilities: two full-size mini PCIe, 2nd
LVDS through MIOe-230, SD card, SIM holder, MIOe with PCIex1, SMBus,
3xUSB2.0, LPC, line out, DisplayPort, and power interface.
MIO-5251 supports various display interfaces including HDMI/DisplayPort, VGA, 48-
bit LVDS/eDP, and rich I/O: 2 x GbE, SATA, mSATA/SD card, 4xSerial Ports, USB 3.0
and 4 x USB 2.0.
