"Randy is EKF2 enabled by default or do we need to enable it?"

Redundant power and logic level translation seems to be missing, and the layout is also changed. The board also suffers from bad accel health so hardware fix still needed."

"I have been using Night Ghost I Am's solution for around 3 weeks now, works totally flawlessly. Insane amount of features have been added and there is still space for more.

"You can probably get one in RMA if you ask nicely."
"You can still test the board on its own. just connect the power board to the pixhawk, and the gps + compass. when outside power it on and see how quick you get a green light. you should at least not have any accel and gyro errors.
you might now…"
you might now…"
"Also, never use the continuity tester of your multimeter on a board like the pixhawk, remember the components are connected and you don't know what voltage is given out of your probes, if its 9V it could damage the 3.3V chips. Also it doesn't help…"
"The pad doesnt seem to be touching, you can use rubbing alcohol to clean the flux core off the board to see clearly.
Anyway i checked the schematic and those 2 caps are connected to the 3.3 sense line, the one we added the 220ohm resistor + bridge…"

"Hi!
No the capacitors should not be bridged. Use your phone with max digital zoom to check that they are not touching the solder bridge or themselves. If they are, just drag your solder iron quickly across where they bridged to free it."

"Ok Dmitry )"
"Dmitry, could you update the main post with the latest working fix, so that people don't try the older fixes you tried that didn't fully fix the issues?
You can use my images to show where to do the fix for the adventurous users."

"You shouldn't have done that fix, Dmitry found that it only partially fixes the problems as you noticed yourself. To fix all the gyro and accel health you just had to do the fix i did above, remove Q601, replace the R621 resistor with a 220ohm and…"
"Hi!
I can confirm that the fix provided by Dmitry Prokhorov works great. Dmitry already merged the fix into the Pixhawk Hardware repo on github, but for those that want a fix for their 2.4.5 board, and can solder SMD without issues, i posted my…"

"So i can confirm that this works great. I was not able to arm after changing battery, nor in cold weather before doing the fix.
I removed Q601, bridged two of the legs as a pass-through and replaced R621 with a 220Ω resistor.
My Pixhawk is from…"

"Ah one last thing, what resistor size is R621? 0603? 0.1%?"
"Roger that, i will give it a try tomorrow and report back. I should get a huge improvement on the bad health errors right? I take more than a few seconds to swap batteries anyway...."
"Like that? :)"
