E1SB25E00000UE from Hosonic Elec, 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 | X'tal | passive | Crystal terminal connected to one side of the quartz resonator (pins #1 and #3 are the X'tal connections); also marks the pin 1 location by the logo. |
| 2 | GND | power_in | Ground connection, shared with pin 4 (pins #2 and #4 are GND). |
| 3 | X'tal | passive | Crystal terminal connected to the other side of the quartz resonator (pins #1 and #3 are the X'tal connections). |
| 4 | GND | power_in | Ground connection, shared with pin 2 (pins #2 and #4 are GND). |
