Navigate to your DFRobot affiliate profile and get your tracking code
All you need is to copy that tracking code, open extension options, go to Platforms / Chinese / Other, and paste it in the DFRobot field.
Then close options, find the product on DFRobot you want to share and click on the extension icon. It will generate an affiliate link for that page. Then you can use bit.ly to shorten that link (if configured) or copy and share it.
