"The MPU9250 is obsolete as is the integral AK8963 mag; has been for quite some time!.
You might want to take a look at Pesky's latest here. They acknowledge the limitations of the proprietary Swiss EL7180 CPU (10mhz CPU) (in addition to…"
"Hate these blatant advertisement posts with virtually no application information. After all, this is Do-It-Yourself-Drones.
FYI MIMO means Multiple Input Multiple Output. I.e., can transmit/receive on three channels (streams) concurrently.
"Yeah. the use of diodes for this is arcane; even multiplexing 5V power inputs as in the PixHawk. Note that if the diodes are properly rated, they won't "burn". Simply put, simple use of a few of today's high power, low cost…"
"Well here is a teaser (you are the first to see it here):
New TBT-AV1 flight controller compatible with ArduPilot/ArduCopter to be released in 2019. Three years in development. Uses Microchip/Atmel SAM E70 300mhz 2MB microcontroller. Multiple…"
"hey Jed, ...mainstream product IN PRODUCTION that YOU would actually use to control your drone/SUAV. No doubt there are dozens of obsolete flight controller designs created in the USA...I designed one in 2010 using three ... yada…"
Precisely! My point is to show the evolution that has taken place in both quad-copters/flight controllers and the market place; not meant to be derogatory towards any particular product. Today a person DOES NOT need a professional and can go to…"
"On the positive side, the money you spent and the money I spent helped to pay for evolution of the market and development of current technology. Same thing happen to early buyers of the automobile. I too have spent LOTS of money on electronics that…"
"GPS uses a radio receiver which operates at about 1.5ghz. As long as no RF blocking material blocks the signal (coming from satellites overhead), the GPS will receive data. RF blocking material; metal or carbon fiber (i.e., electrically conductive…"
Yeah! That's what I was talking about. They use three 24A/190A burst MOSFETS in parallel with a couple of flip-flops set by PWM. Although it is only for 3S, some beefier MOSFETs would fix that.
Additionally, probably some…"
