80386EX Adapter Board 50mm x 50mm
### DESCRIPTION
50mm x 50mm Adapter board for the Intel 80386EX high integration CPU. The 386EX is only available as a PQFP-132, and not everyone is comfortable soldering directly to a main board; e.g., the SBC-386 below.
### TECHNICAL DETAILS / COMPONENTS
This board is NOT a general PQFP-132 adapter; power and ground connections are specific to the 386EX chip. 2mm double row headers are used for mounting: qty 4, 2x17 header strips.
### LEARN / TOPIC / BUILD INSTRUCTIONS
This board fits the RetroBrew SBC-386 v. 2.0 and later ECB (100mm x 160mm) single board computer. This adapter is meant for folks who do not want to solder the CPU directly to the main board.

The predecessor board was 66mm square (2.6" square) using 2 x 17 connectors (4) with 0.1" pin spacing. It was manufactured at PCBway. I will look for the project and share it, if it is not too old for PCBway.
Welcome to share more projects in our community.
I believe the earlier adapter board Gerber file was "Adapter386EX-mfg.zip" Is this file still in your data base for sharing?
Regarding 386EX, I only found two projects you shared in our community. They are the current project and https://www.pcbway.com/project/shareproject/80386EX_Single_Board_Computer.html. Please check.
Not 100mm x 100mm but 2.6" x 2.6" using 0.1" centers on the 2x17 connectors. Contact me through the RetrobrewComputers Wiki under "boardinventory" near the bottom: http://www.retrobrewcomputers.org/doku.php?id=start
