Andrey says we can connect 3 to 5 units to a single output easily. We just need to make a "splitter-cable". > 2/ On Image2, I can see 3 components outside the board near the 6 pin > connector. Is this normal ? Yes this is normal, as layout is not 100% finished yet. If there is no serious objections or additions, we're going to start final layout iteration immediately. It will take about a week more to polish everything. -- Regards, Alexander Chemeris.
