Updated all 132 terminal pins so each Section property now matches its Pin Group.
I also generalized the functional groups:
  • WLAN and Bluetooth → Wireless
  • Debug and main UART pins → UART
  • Status Indication → Status
  • Power Control / Power Output → broader Control / Power Supply
  • USB Boot → USB
Verified afterward that the shown pin metadata has matching Pin Group and Section values across all pages.
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 assign each functional group a consistent Terminal Order and Pin Orientation, with Power at order 1/top and Ground at order 10/bottom, then verify the metadata.
Assigned Terminal Order and Pin Orientation across all terminal pins.
Mapping used:
  • 1 Top: Power Supply
  • 2 Left: Control
  • 3 Right: Status
  • 4 Left: USB
  • 5 Right: UART
  • 6 Left: USIM
  • 7 Right: ADC / I2C / PCM
  • 8 Left: SGMII
  • 9 Left/Right: SD Card, Wireless, Antenna, Reserved
  • 10 Bottom: Ground
Verified Power Supply is order 1/top and Ground is order 10/bottom.
