Notes
When viewing the original schematic for V3 you may wish to read the forum thread that starts here
The main things to note are:
- R6 should be replaced with a 10K ohm resistor.
- You might like to change R2 to .022 ohm and R3 to 7.5K ohm for higher maximum current and to protect the ADC (but remember the caveats about running with high currents, irrespective of whether you change these).
- The R11/R17 and R12/R18 voltage dividers may have the same issues as that of the R4/R6 divider.
