We are happy to announce our new small members of STEP-series, STEP100 & STEP200.
They are our new "products" but you buy the modules from market and you build them, and you upload the dedicated Arduino sketch to it. So we only provide the documents and the source code. All modules are easy to find from markets, and fully compatible with our STEP400 and STEP800.
Enjoy DIY and the full functionality of STEP series with cheapest cost!
For details, please check the documents.
