Frequently Asked Questions:
Q1. Why are these called Arduino Compatible?
A1. The Arduino group demanded us to remove their logos and rename these products so that they do not lead customers to believe they are the same units sold by Arduino
Q2. Are these 100% compatible with the normal Arduino's?
A2. Yes， they really are completely compatible with normal Arduino's. Build quality looks the same and everything (studio， library， tools， etc) just works Type: Relay module borad Package weight: 0.213 kg
