I bought an Adafruit INA260 Current + Voltage + Power Sensor Breakout long times ago, and I’d like to use it in my sck2.1 kit ,but the firmware has INA219 supported, so I’d like to know if it is possible to support INA260.
Hello,
Yes it is possible, it shouldn’t be to dificult using the Adafruit INA260 library. If I have access to this board in the future I can do it, but right now we have a lot of things to do on the firmware side and this it’s not a priority, sorry!
Using the code of INA219 in the firmware as an example, maybe you can give it a try?
Here is a guide to build the firmware.
And relevant files on adding external sensors:
Sensors.h
SckAux.h
SckAux.cpp
Hope this helps!
That’s a good idea for the SCS project I am working on with @oscgonfer. The Voltaic solution Solar power needs voltage and current sensing too. 
The Adafruit INA260 device is a pain. It has IIC but not a grove/qwiic connector, and the PWR/GND leads come out reversed. So you have to use a soldering iron <uugh !>
