hi all, today i finally modded one lite switch with the rp2040. in the tutorial it say to use 0805 47ohm resistor, but i had 0402, so i went up using them.
to solder the resistor, i decided to cut the like that goues to the rp2040 solder point and place the 0402 between the cutted trace. it was my very first manual wire rp2040 job so i cutted some trace i didnt need ( thouth there were needed 4 resistor instead of 3) so i wired back that trace. during the cutting, as the rp2040 has some white text on it i cutted one bad track. the result was blue light followed by 3 yellor. after checking diode mode on all the wire i spot one signal to be 47ohm. so i investigated and found out i cut and put resistor in wrong place. after fixing that problem the switch powered on and actually ift glich very fast
i share some pictureof the final result.
on resistor is in the opposite side, while 2 resistor and in the visible picture. the big wire is the track i fixed.
so in the end yes it's possible to use 0402 resistor and u can cut the trace on the rp2040 to fix them better.
tnx to this great community for the good work and support.
