I have a very bad experience with BAT-3. It has some serous design problems
wich manifest in strange behaviours under EMC conditions - if your power supply
is not very clean, don't use this board. Plus, contacts supplied with it are
low quality - I had simillar behaviour because of loose contacts. And it gets
worse with time.
Finally, we replaced all of BAT-3 (about a dozen) with different design.
