BRIEF DESCRIPTION
This User's Manual describes the hardware of the MBa7x Rev. ≥0200. The MBa7x is designed as a carrier board for the TQMa7x.
The figures in this User's Manual refer to the TQMa7x. All interfaces provided by the TQMa7x are available on the MBa7x.
The function of the i.MX7 can be evaluated, and therefore the software development for a TQMa7x project can start immediately.
The MBa7x supports all TQMa7x modules with i.MX7S (Solo) or i.MX7D (Dual) CPU.
