BRIEF DESCRIPTION
This User's Manual describes the hardware of the MBa8x as of revision 02xx. The MBa8x is designed as a carrier board for the TQ-
Minimodule TQMa8x and essentially serves as a design basis for customer-specific product ideas, as well as a platform to support
development. CPU features and interfaces can be evaluated, software development for a TQMa8x based project can start
immediately.
Core of the MBa8x is the TQMa8x with an NXP i.MX 8 CPU. Currently two i.MX 8 derivatives are supported:
1.
i.MX 8QuadPlus (1 × Cortex
®
-A72, 4 × Cortex
®
-A53)
2.
i.MX 8QuadMax (2 × Cortex
®
-A72, 4 × Cortex
®
-A53)
The TQMa8x connects all peripheral components. In addition to the standard communication interfaces such as USB, Ethernet,
etc., all other available signals of the TQMa8x are routed on 100 mil standard pin headers on the MBa8x.
