Updated the RFFM6901 part metadata with the official Qorvo datasheet URL, manufacturer/package/spec properties, project description, and synchronized terminal pin descriptions/types to the datasheet. The main issue found is a 32-pin datasheet table versus 33 project terminals/footprint pads; the extra GND pin 33 was documented as likely central ground paddle/extra footprint pad for review. Full details are in the RFFM6901 Datasheet Synchronization Report.

33Not listed in pin tableGNDMismatch / extra terminal; likely central ground paddle or footprint pad, but not listed as pin 33 in the 32-pin datasheet pin table.
Terminal property synchronization
Updated terminal properties for pins 1-32 with datasheet-derived Pin Type, Pin Description, Section, Pin Group, and Pin Orientation. Ground pins were corrected from Power Out to Ground; supply pins were set to Power In; CTL1-CTL5 were set to Input; RF input/output pins were assigned RF-oriented descriptions.
The extra GND terminal numbered 33 was not removed. It was documented as Central ground paddle / extra footprint pad; not listed in 32-pin datasheet table so the user can decide whether to keep it as a layout-only ground paddle representation or remove/renumber it.
Footprint and asset cross-check
  • Footprint asset exists and is marked as default footprint: RFFM6901_QOR-M.kicad_mod.
  • 3D STEP model exists: RFFM6901_QOR.step.
  • Symbol asset exists and is default/thumbnail: RFFM6901 RFFM6901_0_1 Symbol.svg.
  • Footprint/pad count observed: 33 pads. Datasheet pin table lists 32 pins and the package/land-pattern information includes a central C pad/metal feature. This likely explains the extra footprint pad, but the schematic terminal numbered 33 should be reviewed because it is not a numbered datasheet terminal.
Flagged mismatches / review items
  1. Pin count mismatch: datasheet pin table = 32 pins; project schematic terminals = 33 due to extra GND terminal with Pin Number 33.
  2. Footprint pad count mismatch: layout reports 33 pads; likely includes the central ground paddle/metal pad. Confirm whether this pad should remain represented as a terminal or should be footprint-only.
  3. Package height discrepancy in public Qorvo data: datasheet text/package drawing indicates roughly 1.175–1.2 mm height, while the product-page parameter table lists 0.975 mm. Use the datasheet package drawing for footprint/3D validation.
Implementation notes from datasheet
  • RF ports are 50 Ω and internally DC-blocked where stated.
  • LNA_BIAS can be left floating for high-bias operation; use 51 kΩ pull-down to ground for low-bias LNA current.
  • Evaluation board uses local decoupling with 0.1 µF and 1 nF capacitors around supply/control rails.
  • Control logic: HIGH min 2.5 V; LOW max 0.3 V.
