Part Review and Datasheet Verification

flux

Completed the E04-400M16S part review and created the report in part-information-review-e04-400m16s. The Datasheet URL was already set, so I did not change it; I confirmed official EBYTE/CDEBYTE sources and cross-checked the 22-pin pinout, key specs, symbol terminals, and footprint.
Open items:
  • The symbol is modeled as 22 separate terminals instead of one module component.
  • Most pin descriptions/types are missing or unspecified.
  • The SDN footprint pad has no explicit position and resolves to 0,0.
  • The footprint pad layout should be checked against the official EBYTE footprint package.
Suggested next steps:
  1. Rebuild this as a single 22-pin E04-400M16S module symbol.
  2. Add datasheet-based pin descriptions and pin types.
  3. Correct the footprint pad coordinates, especially SDN.
  4. Add RF/antenna and VCC decoupling layout guidance.

Add pin metadata from the datasheet: pin number, pin name, pin direction/type, section/group, and pin description.

I’ll update each terminal with datasheet-based pin metadata: number, name/designator, type, functional group/section, and description, then verify the schematic properties.

flux

Metadata was applied; I’m normalizing a few fields to Flux standard property names/options where possible while keeping the datasheet grouping intent.

flux

Added datasheet-based metadata to all 22 E04-400M16S terminals and verified the updates. Each pin now has Pin Number, Pin Role/name, Pin Type, Pin Group, Section, and Pin Description; I used one primary group per pin and normalized pin types to Flux standard values where available.
Open items:
  • The symbol is still represented as 22 separate Terminal components rather than one module component.
  • SPI MISO/MOSI directions follow the EBYTE datasheet wording, which should be rechecked against host/module convention during integration.
Suggested next steps:
  1. Convert these terminals into a single 22-pin module symbol.
  2. Correct and verify the footprint pad coordinates against the official EBYTE package.
  3. Add VCC decoupling and RF/antenna layout constraints.
