Part Review and Datasheet Update

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll review the current part metadata, find and attach the official datasheet if missing, then cross-check symbol pins, footprint, and descriptions against the datasheet and report mismatches.

The part already has a Datasheet URL set, so I’m using that document as the review source and won’t overwrite it unless it proves unofficial or inaccessible.

Completed the BT860-SA part review and saved the full findings in BT860-SA Part Review. The part already had a Datasheet URL, so I did not overwrite it, but I found official Ezurio/Laird datasheet sources and flagged that the current URL is an uploaded PDF copy rather than an official source.

Open items:

Pin types and pin descriptions are all unspecified and should be populated from the datasheet.
Pin 17 is labeled RF, but for BT860-SA it is no-connect.
I2S_WS/PCM_SYNC_ has a trailing underscore.
Project description/version metadata may conflict with newer BT860 v5.0 references.

Suggested next steps:

Update symbol pin types/descriptions from the datasheet.
Rename/fix the pin 17 and pin 19 labels.
Optionally replace the Datasheet URL with the official Ezurio/Laird datasheet URL.
Verify exact footprint pad geometry against the datasheet land pattern.

The part already had a Datasheet URL, so no Datasheet URL property update was required by the user’s condition. The existing URL appears to be an uploaded copy, while official Ezurio/Laird sources are available above.

Footprint review

PCB footprint contains 30 pad nodes, matching the 30-pin datasheet pin table.
Silkscreen/fab outline visible in layout spans approximately 12.85 mm × 8.5 mm, matching the datasheet module body dimensions, with a larger outline/keepout-style shape visible around the module.
Pin 1 marker is present near one corner.
Detailed pad geometry was not exposed in the available structured layout response, so pad width, pad pitch, exact pad locations, and antenna keep-out copper exclusion were not fully machine-verified.

Mismatches / issues flagged

Project description says BTv4.2 while queried datasheet content and distributor listings identify BT860-SA as Bluetooth v5.0 dual-mode. Official search results include both legacy “v4.2” title text and newer Ezurio v5.0 references, so this should be normalized to the current official datasheet revision being used.
All schematic terminal Pin Type properties are Unspecified. Datasheet provides clear electrical directions: GND, Power Input, Input, Output, and Bidirectional. This should be corrected for better ERC/symbol quality.
No Pin Description properties are populated on the terminals. The datasheet descriptions should be copied into terminal descriptions.
Pin 17 is labeled RF in the symbol, but for BT860-SA it is no-connect. This is risky because it implies an RF signal port. Recommended label: RF_NC or pin description “BT860-SA no connection; BT860-ST 50 Ω RF output.”
Pin 19 symbol label has a trailing underscore: I2S_WS/PCM_SYNC_. Datasheet label is I2S_WS/PCM_SYNC.
Datasheet property points to an uploaded PDF copy rather than the official Ezurio/Laird URL. Not strictly wrong because a datasheet URL exists, but an official support or datasheet URL is preferable for traceability.
Manufacturer name is Laird; current branding is Ezurio, formerly Laird Connectivity. Consider updating to Ezurio (formerly Laird Connectivity) or keeping Laird only if matching legacy procurement data.

Recommended fixes

Update terminal Pin Type and Pin Description properties from the datasheet pin table.
Rename I2S_WS/PCM_SYNC_ to I2S_WS/PCM_SYNC.
Clarify pin 17 as BT860-SA no-connect rather than a routable RF output.
Consider updating Datasheet URL to the official Ezurio datasheet landing page or official PDF.
Consider updating project description/version metadata to match the selected official datasheet revision.
If publishing for reuse, verify exact pad geometry against the datasheet land pattern manually or with a layout data export that exposes pad dimensions and coordinates.
