Bill of materials

This is a copy

The original is BOM/BOM.md in the gripper's repository; this page is that file as of 2026-11-04 (commit 37e3488), with the reference images shown inline. If a link is broken or a part is wrong, open an issue there, and the fix lands here with the next sync. The shop's starter kit covers the driver and everything its setup needs.

This BOM lists all components required to build the SSG48 gripper. Quantities are for one gripper.

Note

If any product links are broken, unavailable, or no longer point to the correct item, please open an issue, send us a message on Discord, or contact us via email. You can also use the reference images to find the same or an equivalent part from another supplier.
