I am André Veenstra, electronics engineer and founder of Antratek Electronics.
In this blog you will find boards, firmware and software that I have developed. Most boards have same dimensions and the same interface which allows to make several different systems. These systems can be easily configured for your needs.
You can contact me at firstname.lastname@example.org.
The hardware and software are open source. You can make and modify the products by yourself. Or Antratek can make it for you.
Antratek Electronics distributes embedded electronics and develops custom electronics. More information is available on the website of Antratek Electronics.
