Good News! The all-in-one RasPiComm is getting closer
Thank you for all the views and responses on my original RasPiComm blogpost!
Here I want to explain the RasPiComm hardware. The software part will follow next week.
At the end of the post you will find the schematics of the RasPiComm version 1 and version 2.
If you are not interested in the RasPiComm hardware, take a look at the original RasPiComm blogpost!
Now, let’s start!
