Motherboard Design Guide

Design Guidelines

4.2 Design Guidelines
The following instructions are intended to serve as an aid when designing an application-specific moth-
erboard and ensures the correct and reliable integration of the Module.
While designing a motherboard, consider the following characteristics of the Module:
4.2.1
All ground connections (GND) should be internally connected to the Module (equal potential). It is cus-
tomary to equip the motherboard with a ground plane. All ground connections should be connected to
the voltage supply ground via wide conductive tracks.
A30...A36
B37...B38
Table 4-63
If an earth potential is in place or required, the ground plane should be connected to the earth potential
via one or more capacitors. The use of ceramic capacitors with 100 nF and 100 V is recommended.

• Connector pins [A23], [A24], [A25], [A26], [A27], [A28], and [A29] for +V
ply voltage) should be connected to the fuse via wide conductive tracks.
• Connector pins [A30], [A31], [A32], [A33], [A34], [A35], [A36], [B16], [B37], and [B38] for GND
(ground) should be connected with the operating voltage ground via wide conductive tracks.
• The width of the conductive tracks and the copper coating thickness of the conductors for sup-
ply voltage and motor depend on the current required in your application. A minimum track
width of 75 mil and a minimum copper coating thickness of 35 μm are recommended.
