Are the Ndogo and the LiPo Rider Pro able to get the current battery status?
I want to send a message at the moment the battery is running out…
Ty.
On the Ndogo it is possible to read the battery voltage via the analog input pin A0.
Since the IO levels are 3.3V and the LiPo battery voltage can be as high as 4.2V, the IO pin (A0) is connected to a voltage divider. The resisters and their ratios can be seen in the JST section of the schema:
Additionally, there is a function to read the LiPo voltage in this example:

I’m not sure if the same is possible with the LiPo Rider Pro.
