Looks almost like the first version
This board may look familiar to some of you. Because at first glance, it looks just like its older brother described here: Dividing Head Controller. But many things have been improved in Revision B.
Let’s start with a video. It will tell you most of what I’m going to write about today.
Over the last few weeks I have been quite busy with my MPPT Solar Charger project. I’ve built up a first board and started writing firmware for it. Since the last version was not too different in terms of hardware I was able to re-use most of that code. But I hadn’t even touched on the whole USB stuff back then so there was still a lot of work to do. While the project is still far from being complete I am happy to say that I’ve made quite some progress. Most importantly, the new design seems to work well and so far I haven’t found any mistakes in the board layout. But let’s go through this step by step.
