Bill of materials

This is a copy

The original is BOM.md in the gripper's repository; this page is that file as of 2026-10-31 (commit 9862f62), 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 MSG 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.

Cables

Note

PAROL6 and PAR6 robots use different cables for SSG48 and MSG grippers. Using incorrect one can damage your robot

If you want to build your own cable, use the parts below and follow the wiring guide.

Tip

See the cable building guide in the Assembly manual for full wiring diagrams for both the PAR6 and PAROL6 robots.
