TMDSSOLARPEXPKIT: TMDSSOLARPEXPKIT resistors

Part Number: TMDSSOLARPEXPKIT


On the schematic, I see that some resistors on the Inverter stage have diffrent value than on board.

I try to build just inverter module standalone and do not know which value I should use and why there is that difference?

Resistors R9, R10 are 9k on schematic, but on board they are 4,53k
resistors R15, R18, R19, and R20 are 20k on schematic, but on board 10k

    Hi,

    I will trust what is on BOM and on the board, the schematic may not be up-todate.

    The board was done in express PCB which is not a production environment tool, and hence keeping BOM and schematic in sync was manual effort. 

    For new designs we use Altium where the tool forces us to do schematic change for any BOM change as BOM are auto generates. 

    R9 amd R10 are 4.53K

    R15,R18,R19,R20 are 20k
