I reviewed the part project against the official Quectel hardware design document and used the datasheet as the comparison source, which is the right way to verify part metadata and terminal definitions in a part project
What I updated
  • I found an official Quectel-hosted hardware design PDF and set the project's Datasheet URL to:
    • https://forums.quectel.com/uploads/short-url/xkDIrvPXEAjlmsZJFE4KzSPgwJo.pdf
Key specs from the datasheet
  • Part: BC660K-GL
  • Manufacturer: Quectel Wireless Solutions Co., Ltd.
  • Type: NB-IoT / LTE Cat NB2 module
  • Package: SMD module, LCC/LGA style
  • Size: 17.7 mm × 15.8 mm × 2.0 mm
  • Pin count: 58
  • Supply voltage (VBAT): 2.2 V to 4.3 V, 3.3 V typical
  • VDD_EXT behavior: 1.8 V default, or about 3.1 V to 3.3 V depending on VIO_SEL; up to 40 mA
  • Radio bands: LTE Cat NB2 bands B1/B2/B3/B4/B5/B8/B12/B13/B17/B18/B19/B20/B25/B28/B66/B70/B85
  • TX power: 23 dBm
  • Temperature:
    • Operating: -35 °C to +75 °C
    • Extended: -40 °C to +85 °C
Project metadata review Current state
The project currently has:
  • Designator Prefix = U
  • Manufacturer Part Number = BC660KGLAA-I03-SNASA
  • Manufacturer Name = Quectel
  • Part Type = Transistors
  • Datasheet URL = now set to the Quectel PDF
Metadata mismatches / gaps
  • Part Type = "Transistors" is incorrect.
    • Datasheet/product info describes this as an NB-IoT / LTE Cat NB2 module, not a transistor.
  • Manufacturer Name = "Quectel" is usable, but the datasheet gives the fuller name Quectel Wireless Solutions Co., Ltd.
  • Package or Case Code is missing.
    • It should reflect the module package, e.g. LCC/LGA SMD module.
  • Operating Voltage, Operating Temperature, and Implementation Details are all missing.
  • The project description is not ideal:
    • It says "Cellular GSM, GPRS, LTE Transceiver Module..."
    • The official product summary is specifically NB-IoT / LTE Cat NB2, so the current description is distributor-style and a bit misleading versus the datasheet/product page.
      These are exactly the kinds of property gaps a datasheet-sync audit is meant to catch
Symbol and pin audit
For part-project verification, the important checks are exact pin count, exact pin numbers, and pin-type correctness against the datasheet
Good news
  • The schematic symbol has 58 terminals, matching the datasheet's 58 pins.
  • The PCB footprint also appears to be a single 58-pad footprint, consistent with an LCC/LGA-style module.

Mismatches I found

Pin count58 terminals58 pinsMatch
Footprint styleSingle 58-pad module footprintLCC/LGA SMD moduleMatch
Ground pin typeGND, GND__1 ... GND__9, USIM_GND are set to Power InGround pins are groundMismatch

Reset naming~{RESET}Datasheet calls it RESET_NMinor naming mismatch
Reserved pin namingSplit as RESERVED1, RESERVED2, etc.Datasheet labels these broadly as RESERVED / keep openAcceptable but inconsistent
Pin descriptionsNot populatedDatasheet provides functions/descriptionsMissing
Section / Pin Group / Pin Orientation / Sub-symbol groupingNot populatedRecommended for IC/module partsMissing
Notes on ambiguous pins
A few pins have types that may deserve review, but I would not call them hard mismatches without explicitly reclassifying them from the datasheet wording alone:
  • USIM_DATA
  • ANT_RF
  • GRFC1
  • GRFC2
Pin-description cross-check
The datasheet pin list includes, among others:
  • VBAT pins 42, 43
  • VDD_EXT pin 24
  • GND pins 1, 27, 34, 36, 37, 40, 41, 56, 57, 58
  • USIM_GND pin 10
  • USIM_DATA 11
  • USIM_RST 12
  • USIM_CLK 13
  • USIM_VDD 14
  • RESET_N 15
  • NETLIGHT 16
  • MAIN_TXD 17
  • MAIN_RXD 18
  • PSM_EINT 19
  • RI 20
  • ANT_RF 35
  • DBG_RXD 38
  • DBG_TXD 39
  • VIO_SEL 52
  • GRFC1 54
  • GRFC2 55
  • many RESERVED pins to be left open
That aligns well with the current symbol numerically, but the pin metadata quality is incomplete and in a few cases wrong.
Bottom line Matches
  • Datasheet URL is now set
  • 58-pin symbol matches the datasheet
  • Footprint appears consistent with the module's 58-pad LCC/LGA package
Problems to fix
  • Part Type is wrong
  • Several ground pins are typed incorrectly
  • VDD_EXT is typed incorrectly
  • Reset pin name is not an exact datasheet match
  • Pin descriptions are missing
  • Section / Pin Group / Pin Orientation / Sub-symbol grouping are all missing
  • Several useful project properties are missing: Package or Case Code, Operating Voltage, Operating Temperature, Implementation Details
If you want, I can do the next pass and correct the part metadata plus the terminal properties to match the datasheet more closely.
Fix metadata and pins
Use exact datasheet names
Fill missing properties
Check footprint details
