1.1 Introduction
Figure 1-1: WAFER-EHL
The WAFER-EHL is a 3.5" industrial motherboard equipped with an Intel® Celeron® J6412
quad-core Elkhart Lake processor supporting 4 cores, turbo up-to 2.60 GHz with 1.5M
cache, and supports onboard LPDDR4x-3200MHz with 8 GB memory, up to 16GB.
The WAFER-EHL includes a HDMI1.4 (up to 4096 x 2160@30Hz) connector, a DP1.4 (up
to 4096 x 2160 @60Hz) connector and one IEI iDPM slot for triple independent display.
Expansion and I/O include one M.2 A-key slot for Wi-Fi or Bluetooth expansions, one M.2
B-key slot with SIM holder for 5G module or NVMe storage expansions and one PCIe x4
slot with x2 signal for installing riser card.Two USB 3.2 Gen 2 connectors on the rear panel,
four USB 2.0 connectors by pin header and one SATA 6Gb/s connector. Serial device
connectivity is provided by two internal RS-232/422/485 connectors. Two RJ-45 GbE
connectors provide the system with smooth connections to an external LAN.
