Motherboard Design Guide

The following provides helpful information on integrating the ESCON Module 50/5 on a printed circuit
board. The «Motherboard Design Guide» contains recommendations for the layout of the motherboard
and specifies external components that may be required, pin assignments, and connection examples.

Bring in additional Support:

If you are not trained in the design and development of printed circuit boards, you will need additional
support for this point.
maxon motor will be happy to provide you with a quote for designing and manufacturing a motherboard
for your specific application.

CAUTION

Dangerous Action
Errors in implementing the Design can result in serious Injury!

• Only proceed if you are skilled in electronics design!
• Designing a printed circuit board requires special skills and knowledge and may only be performed

by experienced electronic developers!

• This quick guide is only intended as an aid, does not make any claim to completeness, and will not

automatically result in a functional component!
