Yes, it came while I was away helping with the tARC finals. This was after the initial order was canceled (apparently there was some kind of build error in the first batch of boards he got) and then I re-ordered when he emailed to say they were available.
I have to decide how to proceed with it since its power connector has the opposite polarity of my cells and chargers. Somewhere I need to make a reversing adapter. It's easy to swap the pins in a cell's plug, but then I won't be able to charge it or use it with my Eggfinder IONs (which I built to be compatible with my existing cells and chargers by putting the power socket on the board the other way 'round from how Cris' documentation calls for).
Marcelo has been responsive to my questions and comments so far. I am a little disturbed about his comment in his post above that the thing is designed to be powered up while the rocket is on the pad, which is pretty awkward operationally at least for models like I like to fly. The device will fit in a BT-50 tube, and I think it still will with the cell plugged in to power it. But it would be a pain to put, say, the Nova Payloader on the pad with the nose cone off, power the thing up and slide it down into the payload section without jostling it too much, putting the nose cone on and securing it, then flying.
It does say this clearly in the manual, such as it is: "WARNING: DO NOT BOOT THE BOARD IN FLIGHT MODE UNTIL YOU ARE READY TO FLY AND THE BOARD IS POSITIONED IN THE ROCKET TO AVOID FALSE DETECTIONS." So it's not a secret. It's just not the way I'd prefer to do it.
I'm also wrestling with the requirement for Java 17 for his Mission Control Software as that version is not the version that is part of MacOS. But I did get the software running on the little Windows 10 ThinkPad that I take to the field for use with altimeters and such, so I can play with the software as soon as I decide where to insert a polarity-reversing adapter in my "altimeter infrastructure" or remove the power socket from the Starlight Mini and put it back on the other way around. I'd rather not do that, yet, so I see making a reversing adapter in my future....probably later today.
How's that for a long answer to a short question?
