XL7EL89CMI-111YLC-24M from Yangxing Tech, in a SMD2016-4P. 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 (pad #1), connected to one side of the crystal; the Top View Crystal Connection diagram shows #1 and #3 as the crystal pads. |
| 2 | GND | power_in | Ground pad (#2), labelled GND in the Top View Crystal Connection land pattern diagram. |
| 3 | XTAL2 | passive | Crystal terminal (pad #3), connected to the other side of the crystal; the Top View Crystal Connection diagram shows #1 and #3 as the crystal pads. |
| 4 | GND | power_in | Ground pad (#4), labelled GND in the Top View Crystal Connection land pattern diagram. |
