Description
Description
This is my design for a voltage monitor and boost converter to boost 7.4v NP-F970 batteries to power audio mixers and recorders.
It has 2 i2c voltage / current sensors - on on the input Battery voltage, and one on the post boost converter voltage. You can choose to use both, or brige and not populate any you do not wish to use.
It has footprints for several different boost converters.
This builds on my previous version.
