"HiI have a funny issue with mission planner; setting waypoints by clicking on the map is VERY unreliable; most of the time it just plain doesn't work. I can set 1-2 waypoints, and after that, waypoint-adding is mostly ignored. Other dialogue…"

Power tolerance on APMv2 from BEC

Hi *I want to add a BEC into my Quad as I'm getting a marginal voltage from the ESC's onboard BEC. The ESC/BEC gives me 4.7 as measured on the APMv2 and I'm nervous of reboots and drop-outs, so I got…Continue

The intention is to do something like this (using lousy ASCII-art for the diagram)

This forms a string of…"

Mark Murray commented on emile's blog post Add a backup battery on the MTK GPS module."Hi
This is good news! It looks like something very similar can be done on APMv2, except that there is a convenient resistor to remove (R3) giving a pad to connect the battery to.
I'll probably go a step further by using a 1F SuperCap in place…"

With a 15R load (so 0.33A) the Turnigy BEC's voltage drops to 5V. What current does the APMv2 draw, please?
Hmm. This may be worth making a multimeter probe for. (Way make one? I'm disabled, with dodgy hands, and I don't…"

Hi *I want to add a BEC into my Quad as I'm getting a marginal voltage from the ESC's onboard BEC. The ESC/BEC gives me 4.7 as measured on the APMv2 and I'm nervous of reboots and drop-outs, so I got a Turnigy 5V/3A dedicated BEC. Problem is, its measured open-loop output voltage it 5.27 volts. Normally I'd use this (I have some digital experience), but after a few dire warnings about not "over-volting" the APMv2, I'm checking here.Is 5.27V too much? Will it take out the APMv2?I'm aware of…See More

2.5.5-Beta is looking really good for me! Thanks for the good work!

Mark Murray replied to Randy's discussion MPU6000 scaling issue"Most excellent, thanks! :-)
The soldering was easier than thought, but I planned it properly, and used connectors to make it possible to more easily remove the sensor.

Mark Murray replied to Randy's discussion MPU6000 scaling issue"Andy,
The flow sensor has been relocated on the APMv2, and is currently advertised as "supported in 2.6+". I'm hoping that a patch release will provide this support earlier, if 2.6 is going to be delayed for any reason.

Mark Murray replied to Randy's discussion MPU6000 scaling issue"Please confirm that the APMv2/FlowSensor patch is also NOT in this 2.5.5 release?
Thanks
