In OpenEVSE v5 schematic, R4 and R22 resistors values are 200K.
But from the OpenEVSE v5 documentation PDF, one can verify they are mounted as 330K resistors. Please double-check the schematic.
I understood from the context and other forum posts they are flameproof resistors as well.
So my question is which is R4/R22 part number?
Thanks in advance.
Values and tolerance of parts on the boards manufactured by OpenEVSE change over time based regulatory, safety and in-house testing. The original design was 200K.
If you are spinning your own version, you will need to determine the value and tolerance of each component to meet you own specific needs.
