The Story of Otronic
Otronic was founded by Michael Otto and specializes in online sales of hobby electronics, particularly focused on microcontrollers such as Arduino, ESP8266, and ESP32. Michael’s passion for electronics began back in 1985 at the age of 7, when he received a Kosmos Electronics X2000 kit.
After years of working mainly with computers and IT, his passion was reignited with the rise of Arduino in 2004. In 2015, Michael founded Otronic and was able to turn his hobby into a profession.
At Otronic, service and quality are top priorities. All products come with a 1-year warranty, and orders can be returned free of charge within 30 days—no explanation needed. With this no-nonsense mindset, customers take zero risk.
