**Molex** · SL header with latch, right angle, 1x4, 2.54 mm · Molex_SL_70553-0003_1x04_P2.54mm_Horizontal

0705530003 (70553-0003) from Molex: SL header with latch, right-angle, 1x4, 2.54 mm. The footprint follows Molex's recommended PCB layout; the 3D model is Molex's own STEP, posed by Adom.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Contact 1 of 4, 0.64 mm square pin at 2.54 mm pitch (SL right-angle header). SDA-70553-XXXX rev M does not number the contacts and the header is symmetric about its centre; contact 1 is the end on pad 1. [datasheet p.1] |
| 2 | 2 | passive | Contact 2 of 4, 0.64 mm square pin at 2.54 mm pitch (SL right-angle header). SDA-70553-XXXX rev M does not number the contacts and the header is symmetric about its centre; contact 1 is the end on pad 1. [datasheet p.1] |
| 3 | 3 | passive | Contact 3 of 4, 0.64 mm square pin at 2.54 mm pitch (SL right-angle header). SDA-70553-XXXX rev M does not number the contacts and the header is symmetric about its centre; contact 1 is the end on pad 1. [datasheet p.1] |
| 4 | 4 | passive | Contact 4 of 4, 0.64 mm square pin at 2.54 mm pitch (SL right-angle header). SDA-70553-XXXX rev M does not number the contacts and the header is symmetric about its centre; contact 1 is the end on pad 1. [datasheet p.1] |
