Terms of Use

Last updated: November 2026

rbgrid.io is an informational and documentation website for the RBgrid firmware project, operated by ZHUHAI ROBOTDYN TECHNOLOGY CO., LTD. By using it you agree to these terms.

1. No sale here

This site does not sell products or take payments. Hardware is sold on rbamp.com and on our AliExpress store, each under its own terms of sale, warranty and returns. Links out to those stores are for your convenience.

2. The software

RBgrid firmware is source-available under the PolyForm Noncommercial 1.0.0 licence — free to use, modify and build for personal and non-commercial use; commercial use requires a licence (info@rbamp.com). The rbAmp module libraries are MIT, separate from that licence. See the licence section, LICENSE, COMMERCIAL.md and NOTICE in the repository. The RBgrid name and logo stay with the project; forks are renamed.

3. Content "as is"

Documentation, prices and specifications are provided in good faith and may change. Recommended prices shown here are indicative; current prices are on rbamp.com. We give no warranty that the information is error-free or fit for a particular purpose.

4. Electrical safety

RBgrid measures mains circuits. For any work inside an electrical panel, call a qualified electrician. You are responsible for safe and lawful installation and use.

5. Liability

To the extent permitted by law, we are not liable for indirect or consequential loss arising from use of this site or the information on it.

6. Changes and contact

We may update these terms; the current version is posted here. Questions: info@rbamp.com.
