LevelShifter capacitors details #12

Closed mateuszradomski closed 2 years ago

Hi,

I'm having trouble finding the specific capacitance values for the 12 capacitors on the level shifter. What should I consider when picking out those when I want to build a level shifter myself.

Hi!

My mistake, I forgot to add the values to the schematic 🤦 I will update it this evening.

Those are 100nf ceramic 0603 SMD decoupling capacitors. The value/voltage is not critical, anything from 33nf to 470nf and 6v to 50v will work.

These ones will do the job:
