2520-24-20-10-10 from Suzhou Liming Elec, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XTAL1 | passive | Crystal terminal 1 of the 2.5 x 2.0 mm SMD crystal, marked #1 on the bottom view. |
| 2 | GND | power_in | Connected to the metal cover; the datasheet says #2 and #4 should be connected to ground. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 2.5 x 2.0 mm SMD crystal, marked #3 on the bottom view. |
| 4 | GND | power_in | Connected to the metal cover; the datasheet says #2 and #4 should be connected to ground. |
