"Hi, Guys Chris - That's great to learn. A guaranteed compatible power source. Is it backwards compatible to APM 1 & 2.0?Peter Chaffe - mostly it is about having a known good power source.Chris/Peter Meister - I think a large minority…"

"some questions: atmega2560 costs 5x the 328P, so wouldn't it make more sense to use 328P + 4051 or 4067 MUX for voltage/current sensing? Or is it the same uC to be used, not the separate-one? uC controlled battery switch, where the same uC is…"

"I plug all 4 BECs from my 4 ESCs into my APM2.0.  I haven't had an issue at all with power.  Not sure why I would want to add the extra weight and complexity to my quad. "

"Peter, it's just designed for a single battery input (to keep it small and inexpensive; almost all users have a single battery). But if there's enough demand for a dual battery version, we'll add that, too. "

"Chris, glad to hear of the APM power supply. This will solve a lot of problems for those just starting. Hopefully it will include dual battery supply inputs for fault tolerance :)"

Peter Chaffe commented on John Edmonds's blog post APM 2.x Power management and Distribution system
"John, I can understand that your motives are good but I can't see the APM2.5 requiring the complication of any advanced power supply unit. The specs say 5v0 -+ 0v5 ie 10% so what is special about that?All esc becs that I've tested had…"

"John, great post and analysis. Just wanted you to know that 3DR will be releasing an APM power supply (with integrated voltage/current sensor) in a couple weeks. It will come standard with the board, too."

APM 2.x Power management and Distribution system

Hi, All I want to test the water and learn how much support is out there for a power management and distribution system for the APM 2.x. The APM 2.x is now a well understood and reliable FC. Maybe now it is time to design a stable and reliable power system for it?There are far too many threads and comments in the forums…See More
