SWXJHBCVE0-32.768000 from Starwave(思大), in a HC-49S-SMD. 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 | First crystal terminal (left pad in the bottom-view drawing); the crystal is non-polarized with a 18 pF load capacitance unless otherwise specified. |
| 2 | XTAL2 | passive | Second crystal terminal (right pad in the bottom-view drawing); the crystal is non-polarized with a 18 pF load capacitance unless otherwise specified. |
