Providing Power to External Components
Posted: Wed Feb 06, 2019 3:55 pm
Hi and thanks for any help you can provide.
My question is about the voltage and providing power to a new sensor or motor I may add:
From the Power Distribution Section on the Hardware Explained page
(https://wiki.bitcraze.io/projects:crazy ... :explained)
From that table:
Use the digital supply for a component rated <100 mA. So hook up between VCC and DGND.
For <1 A, use VCOM and GND.
I usually think of COM as 0 Volts, but here it seems I should hook my + up to either the VCC or VCOM and the - to GND or DGND. Is that correct or is there a reason for the difference?
Is this the best way to power external electronics? Seems like there's a lot of warnings about using LiPos so I didn't want to tie directly into the +BATT. I also wasn't sure if I could use the analog signal as an option.
Background:
I'm using this as a platform to learn more about embedded controls and C. That's why I'm working on adding other motors, sensors and components, besides just using it for flying.
I did go through the schematics for the decks. So for example the LED-ring schematic shows VCOM going to VIN on a chip on the deck. So I think I'll be ok, but I'm not 100% certain I have it right .
But I really want to make sure I don't damage my new prized possession!
Thanks again for any help you can provide, hope this is helpful for others as well.
