Datasheet Pin Review


Created a project doc
Completed the datasheet review and grouped all 38 pins by primary function with no duplicate pin assignments. The official Morse Micro datasheet URL was already set; I updated terminal Pin Type, Section, Pin Group, and Pin Description fields from the datasheet.
Full findings are in MM8108-MF15457 Part Review. Main flagged issues: library classification metadata looks inaccurate for an RF/Wi‑Fi HaLow module, but the symbol pinout and 38-pad footprint match the datasheet.
  • Make the functional group more general.
  • Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property.
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
I’ll simplify the pin groups, mirror each Pin Group into Section, then assign terminal order and orientation by group with Power at the top and Ground at the bottom.
Updated all 38 pins as requested.
  • Generalized groups: Power, RF, Control, Debug, Communication, GPIO, Ground
  • Set every pin’s Section to match its Pin Group
  • Assigned Terminal Order: Power = 1, RF = 2, Control = 3, Debug = 4, Communication = 5, GPIO = 6, Ground = 10
  • Set Pin Orientation: Power = Top, Ground = Bottom, and remaining groups distributed between Left/Right
Verified the updated properties on the schematic terminals.
