EVA-M8M-0 Part Validation Report

Date: 2026-07-22

Scope

Reviewed available Flux/library part information for EVA-M8M-0, checked the existing datasheet setting, and cross-checked the schematic symbol terminals, PCB footprint, and pin metadata against the u-blox EVA-M8 FW3 Data Sheet.

Primary datasheet evidence:

Current official u-blox datasheet: https://content.u-blox.com/sites/default/files/documents/EVA-M8-FW3_DataSheet_UBX-16014189.pdf
Document: EVA-M8 FW3 Data Sheet, UBX-16014189, R07, 18-Jun-2025
Product/type covered: EVA-M8M, type number EVA-M8M-0-10
Existing datasheet state observed from library search: Datasheet URL is set to the official u-blox PDF above.
Existing datasheet state observed from project semantic index: a Google Storage uploaded PDF copy was also indexed. No datasheet overwrite was performed because a Datasheet URL already exists.

Mismatches / issues flagged

Description sensitivity appears wrong for EVA-M8M-0. The library/project description says -167dBm, but the datasheet reports EVA-M8M tracking/navigation sensitivity as -164 dBm for GPS+GLONASS/GPS. The -167 dBm figure belongs to EVA-M8Q GPS+GLONASS, not EVA-M8M.
Pin Type metadata is incomplete. Every terminal currently has Pin Type: Unspecified; the datasheet provides I/O directions for each pin.
Pin Description metadata is missing. Terminal-level Pin Description properties are not populated with datasheet descriptions/remarks.
Package / Case Code is not set in indexed project properties. Recommended value: LGA43 or 43LGA.
Operating Voltage and Operating Temperature properties are not set in indexed project properties. Datasheet-backed values are available: VCC/VCC_IO 1.65–3.6 V, VDD_USB 3.0–3.6 V, V_BCKP 1.4–3.6 V, operating temperature -40 °C to +85 °C.
Manufacturer classification is inconsistent. The explicit Manufacturer Name property is u-blox, but the library manufacturer facet is Other.
Part subtype / IC function classification is wrong. Library reports subtype/values like Logic and logicFunction: AND, which do not describe a GNSS receiver module.
Footprint description text says 42-TFLGA. The actual pad count and geometry match LGA43, but the descriptive string should be corrected to LGA43.
Product lifecycle should be reviewed for new designs. The u-blox product page reports the EVA-M8 series as no longer available, even though the datasheet is current and production-information status is present.

Overall result

Symbol pin numbers/names: pass, all 43 terminals match the datasheet pinout.
Footprint geometry: pass for pad count, body outline, pad pitch, pad sizes, and inner ground pad arrangement.
Metadata quality: needs cleanup, especially sensitivity in description, pin types/descriptions, package code, manufacturer facet/classification, part subtype, and lifecycle note.
