1.1 Introduction
Figure 1-1: WAFER-TGL-U
The WAFER-TGL-U series is a 3.5" form factor single bard computer. It has an on-board
11th generation Intel® Core™ i7/i5/i3 or Celeron® processor, and supports one 260-pin
3200 MHz dual-channel DDR4 SDRAM SO-DIMM slot with up to 32.0 GB of memory.
The WAFER-TGL-U series includes two HDMI connectors, a DP connector and an iDPM
connector for quadruple independent display.
Expansion and I/O include one M.2 B-key slot supporting 5G module, one M.2 A-key slot
for expansions, four USB 3.2 Gen 2 connectors on the rear panel, two USB 2.0
connectors by pin header and one SATA 6Gb/s connector. Serial device connectivity is
provided by one internal RS-232 connector and two internal RS-232/422/485 connectors.
Three 2.5GbE RJ-45 connectors provide the system with smooth connections to an
external LAN.

2.1 Anti-static Precautions
WARNING!
Static electricity can destroy certain electronics. Make sure to follow the
ESD precautions to prevent damage to the product, and injury to the
user.
Make sure to adhere to the following guidelines:
Wear an anti-static wristband: Wearing an anti-static wristband can prevent
electrostatic discharge.
Self-grounding: Touch a grounded conductor every few minutes to discharge
any excess static buildup.
Use an anti-static pad: When configuring any circuit board, place it on an
anti-static mat.
Only handle the edges of the PCB: Don't touch the surface of the
motherboard. Hold the motherboard by the edges when handling.
2.2 Unpacking Precautions
When the WAFER-TGL-U is unpacked, please do the following:
Follow the antistatic guidelines above.
Make sure the packing box is facing upwards when opening.
Make sure all the packing list items are present.
