R2, R3, R4 and R7 #4

Does anyone know why the list of materials does not show the resistances r2, r3, r4 and r7 and in the gerbers yes? Can the plate be mounted leaving those resistors unmounted?

marplukiwi commented 1 day ago

According to the circuit diagram, the resistors are not needed

According to the circuit diagram, the R18 is not needed either

Ok, so leaving those resistors without mounting, the gamma bitaxe should work without problems, right?

marplukiwi commented 1 day ago

If the documentation, i.e. the circuit diagram, is correct then yes. But I cannot confirm this.

Ok, I'll try to mount it without those resistances to see if it works. Thank you for the help.

@skot dear skot, what do you say about this?

skot commented 21 hours ago

@marplukiwi is correct, R2, R3, R4 and R7 are DNP meaning "Do Not Place".

marplukiwi commented 16 hours ago

@skot and R18 DNP or not? R18 is in the BOM but crossed out in the circuit diagram.

The red X in KiCad means DNP
