What's New?
This edition of the V5 Flight Controller Board...
Burnwire and Heater Circuit Update!
We had a bit of an embarrassing issue with the V5a Boards where we were trying to use max 5.5V load switches to control battery voltage which could be as high as 8.4V! We are now introducing these fancy new automotive load switches from Ti that could could go as high as 40V!
Load Switch Switchup
On the V5a we used the AP22652 which is an
ENABLE_LOWload switch. This creates a quite confusing situation in the code where to enable the load switch you have to pull the pin with apin.value = Falsestatement. To avoid this confusion we switch to using the AP22653 to try and clarify this situation.What New Software Needs to be Implemented
