TX 3.13 Schematic
#1
Is a schematic available for the TX PCB v3.13, it's quite different from the v3.12?

Thanks Andy

Hi Andy,

You are right, seems I forgot to publish it.
It's here now: https://www.meteocercal.info/forum/Threa...Schematics

Hello, a quick question about this board: I’m looking for install all electronic components, but I don’t have 3K resistors , do u think it’s ok if I put 3.3K value instead of 3K in the R3  Or I must use 2 resistors in serial to achieve that 3K ohm value ?

If you don't use the 3k value then it will affect the accuracy of the battery voltage reported, you could then compensate for this in software but then it would be non standard and you would have it make this change at every update, I would recommend you make a 3k resistor with a series combination..

Hi, I will do it with series combination , thanks for your quick replay and help
