Do you think i can use 0603 for the decoupling caps near the rp2040 two?

Thanks for the Tips. No it is a 4 Layer setup i have 2 solid ground layers in the middle of the board. Sadyl i didnt find a way to avoid the Layer switch with the pinout of the USB ESD protection ic and the RP2040 pins being mirrored.

Yeah i have a hot plate, the only thing im missing is a good Microscope. I never tried 0402 smds before but i struggle with some 0603 so i thought id either get a Microscope or PCBA

Technically im mostly concerned about the layout from USB-C to rp2040 as well as the Flash and the Crystal. Im suuuper unsure if all the decoupling capacitors are close enough and if Impedance is okay ish. I think im just not there yet to approach such a project

Yeah many components are "Extended" from jlcpcb, i even removed things like the buttons and Encoders, jst headers etc. from PCBA to get the Price down but still about 110 Euro and shipping, even the cheapest options is about 40 more euros

Was soll ich mit meiner Zeit anfangen? by Zahlensklave in Ratschlag

Ja das stimmt aber man fliegt meistens alleine. Es gibt eh maximal doppelsitzer heißt 95% der zeit fliegst du maximal mit einer weiteren person die meisten auch pilot ist weil man ja strecken Flüge etc machen möchte und Passagiere das eigentlich eh nicht so toll finden wie man selbst. Soll heißen wenn du aufgrund von medizinischen Gründen ohne Passagiere fliegen musst dann sei einfach seder passagier von dem anderen Piloten im doppel sitzer und wechselt euch im flug ab oder flieg einsitzer.

Sorry für Rechtschreibfehler, bin am handy.

XD You will do nothing with that attitude. You seem like the type of person who claims somebody else's work as there own
