Functionality
Core of the MBa6ULxL is the TQMa6ULxL, which is based on an NXP i.MX6ULx CPU. In addition to the standard communication
interfaces like USB, Ethernet, RS-232, etc. other signals and interfaces are routed to two 20-pin 2.54 mm headers.
The MBa6ULxL provides the following interfaces and functions:
