This is just an observation, as I don't have an sBIT at the moment.? (I am planning on getting one, likely near Easter next year.)? I am comparing an item on the Xiegu X6100 with the sBIT. The Xiegu displays the battery voltage, and will shut down to protect the internal battery when the voltage gets too low.? Any thought on adding at least a display on the sBIT?

Hi Gerry,

I don’t think there is a direct way to monitor the sBitx source but I could be wrong. ?The voltage from a DC source is immediately converted to lessor voltage regulation for the RPi, etc. ?My sense is a monitor circuit that reports on the I2C interface could be developed but it might be impossible to mount in the V2 enclosure.

Since the battery will be external anyway, I’d build a monitor in line with the battery. ?I’m not sure I’d build in an automatic disconnecting means (relay, etc) but I would certainly build in an audible alert. ?I’d likely print a custom box that houses the battery and electronics.

For what its worth, Scott ?

ADC0 on the ATTiny85 PB5 isn't being used.? I don't see why this couldn't be used to monitor input voltage if one wanted to do so. You'll need to set RSTDISBL fuse bit, and have or build a high voltage programmer to reset the fuses if you need to re-program at a later date.
Rgds,
Gary
