BOM Light Unit #2 Rev.4 | changed parts

[1N4003]

Hi,

I just wanted to ask if the changed parts between Light Unit #2 Rev.3 and Rev.4. (Resistor 3.9K 0.125W & Capacitor 330µF 25V) make a significant difference operation wise. If so, where does the changed capacitor and resistor go? The BOM section for Rev.4 doesn't mention positions and the BOM.csv file is still on Rev.3

Thanks in advance!

Appears the 330uf cap is placed into C2 on the PCB.
Cannot find where the 3.9K resistor is to be placed as R1 = 2k, R2 = 2.2k and R3, R4 are 4.7K.

Oh, ok. Didn’t see that, sorry. Still learning the ropes here. I’m curious, what was the reason for revision #4 of the light source and the partial exchange of parts? Thanks for the awesome project by the way!
