We have  a few of partners who share license of firmware, managing tool, etc.

The vendors which are not listed are not our partner or legally licensed.

There are 2 ways to use our RGB firmware legally.
– Purchasing Attin85 chip with firmware uploaded from me($2 per chip)
– Purchasing the license to use it ($150 per year for only one project or model)

If you have any question, please contact me(

I hope you to understand the above policy.
It’s the least method to protect our proper buyer from  feeling “ripped-off” since so many makers copy our products and provide them at quite low price.
