Mismatch in BOM and SCH #17

Open dikdom opened 7 months ago

dikdom commented 7 months ago

Hello, in rev 1.10, R29 is 2M2 on schematics and 1M in BOM. Which is the final source of truth? :)

Resistor networks are RP1, RP2 and RN3. Why are the different notation?

Is there any significance to have tantalum capacitors instead of normal aluminium (electrolytic) ones?

Thanks, Dikdom

both 1M and 2M2 will work, but the schematic is leading, I thought I already fixed this issue, I will check. both resistor pack (RP) and resistor network (RN) mean the same thing. In this design I only use aluminium electrolytic capacitors. but if you only have tantalium electrolytic capacitors, you can use these too (if they have the right capacitance and voltage value).
