Read BOM.

Read schematic.

Read layout.

I reviewed the available part data for BHI360, the existing symbol terminals, and the footprint.

Symbol cross-check

CheckResultNotes
Terminal countPassSymbol has 20 terminals, matching datasheet
Most pin names/numbersPassHost, aux, debug, reset, reserved, and interrupt pins line up with datasheet
Power pin numberingMismatchVDDIO is set to pin 5 but datasheet says pin 8. VDD is set to pin 8 but datasheet says pin 5
Ground pinsPassGNDIO = 6, GND = 7, matches datasheet
VREGPassPin 9, matches datasheet
Pin descriptions in symbol metadataMissing / incompleteAll terminals appear to have no pin description text populated
Pin electrical typesIncompleteAll terminals are marked Pin Type: Unspecified

Footprint cross-check

CheckResultNotes
Pad countPassFootprint has 20 pads
Pad names to terminalsPassPad names map to symbol terminal names
Package stylePassLGA footprint matches datasheet package style
Outer / inner pad structurePassIncludes outer ring pads plus inner pads 15-20, consistent with datasheet note
Pad sizingPassUses 0.250 x 0.475 mm, 0.475 x 0.250 mm, and 0.250 x 0.250 mm pads, matching the datasheet footprint recommendation
PitchPass0.5 mm pitch matches datasheet
Pin-description notes from datasheet
A few important descriptions worth carrying into the symbol metadata:
  • RESETN: active-low reset
  • HCSB: host SPI chip select / protocol select, keep high for I2C
  • HSDO: host SPI MISO / host I2C adr0
  • M3SCL: debug / I2C SCL / JTAG clock related multiplexed function
  • JTAG_DIO: JTAG data I/O
  • RESV1 and RESV2: datasheet marks these as reserved / do not connect

Summary of mismatches and concerns

SeverityFinding
HighVDD and VDDIO pin numbers are swapped versus the datasheet
MediumSymbol terminals lack populated pin descriptions
LowSymbol electrical pin types are all unspecified, which reduces ERC usefulness
InfoDatasheet URL is already present, so no web lookup/update was needed
If you want, I can next help you fix the swapped VDD / VDDIO numbering and draft a clean pin-description table for all 20 terminals.
Fix swapped power pins
Add all pin descriptions
Set pin electrical types
