SIM7070G Pin Grouping

flux

Yes. I’ll assign every pin to exactly one broad functional group based on its primary datasheet function, keep Section equal to Pin Group, and avoid duplicates across groups.

flux

Grouped all 68 pins into 14 functional groups, including Power, Ground, UART, USB, SIM, I²C, GPIO/SPI, RF, Analog, Control/Status, PCM, and NC. Each pin appears exactly once; Section matches Pin Group, orientations are consistent, and pin numbers/types/footprint mappings remain unchanged.

  • Make the functional group more general.
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.

flux

I’ll consolidate the pins into 10 general groups, assign one group-level Terminal Order from Power = 1 through Ground = 10, and alternate the intermediate groups between Left and Right.

flux

Reorganized all 68 pins into 10 general groups with Power = Order 1 / Top and Ground = Order 10 / Bottom. The remaining groups alternate between Left and Right; every pin belongs to exactly one group, and each Section matches its Pin Group.
