Mini Minim OSD / Current sensor
#1
Hi.

I've read a lot about Micro MinimOSD but the information is different from one site to another.
I need to know what kind of current sensor I need.
Do I need a current sensor that outputs 0.0 - 3.3V 
or one that outputs 0.0 - 5.0V.
Thanks.

Do you have examples of these current sensors that outputs different voltage?

Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider.

Signal (0.5V)

The ATmega328P is a 5V device, so it can take the full range of 0 - 5V, but you can still use 0 - 3.3V with it, it just needs to be calibrated accordingly.

an osd, of any kind... or telemetry... depends where you want to show it.

also V on battery is more useful than Amps... as you land when V is getting low Smile
All the best
