CMOS Logic Levels
The boards cB-0701-01 and cB-0702-01 has some signals that are defined as logic level
CMOS signals. The boards are designed to be fully interchangeable between each other.
This is possible if the host product has made space for the cB-0702-01 board. This makes it
possible to choose freely between a class 1 or class 2 device without any change of the host
product.
