**Abracon LLC** · Pre-ordered Products · SMD2520-4P

ABM10W-25.0000MHZ-6-B1U-T3 from Abracon LLC, 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 (pin #1 at top-left of bottom view); the datasheet does not label it, it is one of the two crystal connections. |
| 2 | GND | power_in | Pin #2 is GND per the bottom-view drawing (case/ground connection). |
| 3 | XTAL2 | passive | Crystal terminal 2 (pin #3 at bottom-right of bottom view); the datasheet does not label it, it is the other crystal connection. |
| 4 | GND | power_in | Pin #4 is GND per the bottom-view drawing (case/ground connection). |
