Datasheet Pin Review
-
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.
Thought for 16 sec
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.
Worked for 2 mins 36 sec
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.

Datasheet cross-check results
Symbol and pin table
- Pin count matches the datasheet: 38 terminals present.
- Pin names and pin numbers match the datasheet pin description table.
- Pin type fields were originally unspecified; updated from datasheet-derived functions.
- Pin descriptions were missing/unspecified; updated with concise datasheet-based descriptions.
- SDIO alternate SPI functions were captured in pin descriptions.
- RESET_N and WAKE are control pins in the VBAT domain per datasheet note.
- SDIO bus note: all SDIO bus pins except SDIO_CLK should be pulled up with 10 kΩ to 100 kΩ when used as SDIO, per the datasheet.
Footprint
- Footprint pad count matches: 38 pads.
- Footprint pad size matches: 0.6 mm x 0.6 mm square pads.
- Footprint pitch matches: 1.0 mm around the module perimeter.
- Footprint outline matches: 11 mm x 10 mm nominal module footprint.
- Pin-1 marker is present near the pin-1 corner.
Mismatches / issues flagged
- Library classification metadata appears inaccurate for this part: the part is an RF / Wi-Fi HaLow module, but the library search metadata reports Integrated Circuits -> Logic with a logicFunction of AND.
- The manufacturer facet from library search showed Other, while the Manufacturer Name property correctly says Morse Micro.
- The symbol terminal Pin Type fields were all Unspecified before this review; these have been corrected.
- The exact package/case metadata property was not visible in the terminal-level schematic data, although the footprint asset itself matches the datasheet mechanical/pad pattern.
