1.1 Introduction
Figure 1-1: WAFER-BT-E38xx1W2
The WAFER-BT-E38xx1W2 motherboard is an Intel®Atom®processor platform which
supports wide-range operating temperature (-40°C – 85°C). It has 2 GB or 4 GB
1066/1333 MHz DDR3L soldered-down memory.
The WAFER-BT-E38xx1W2 includes a VGA connector, a LVDS connector and an iDP
connector. Expansion and I/O include one USB 2.0 connector and one USB 3.2 Gen 1
(5Gb/s) connector on the rear panel, four USB 2.0 connectors by pin header and two
SATA 3Gb/s connectors. Serial device connectivity is provided by one internal RS-232
connector, one external RS-232 connector and one internal RS-422/485 connector. Two
RJ-45 Ethernet connectors provide the system with smooth connections to an external
LAN.
