First of all I wanted to thank you for your work. I'm building your DRV8825HW203_M-MT-F-BT-11 pcb version focuser. and I have a doubt about the voltages of these capacitors C1 Capacitor 0.1uF and
C2 Capacitor 0.33uF. I have been looking on the internet and I have seen that there are varion voltages and I do not have the necessary level to know it.

Thank you.

C1/C2 are ceramic type capacitors - on ebay these are fine

Gracias ;-) one more question, C3/C4 and C5 in the scheme it puts a value of 35v and in the list it puts 16v, 25v y 35v respectfully. Which one do I listen to?

Hello again. Another question, according to the diagram you use a 7808 voltage regulator. This is 8v, correct? no problem with the arduino? Tx
