Can anyone point me in the direction of a list of parts for the rp2040 mod chip? I got one of the blue pcb ones without the ribbon cables and I need to know the sizes of resistors and mosfet. I know it’s the surface mount ones. And also is there any other parts I need that I didn’t mention? Thanks for the help in advance

    It’s unclear to me how the blue ones are supposed to work? Are you just going to wire stray wires to the appropriate places and put mostfets there? That sounds dreadful. Soldering to the already tinty pads next to the processor with a ribbon cable was already a pain, I don’t see a reason your should pay more to subject yourself to a worse experience.

    I heavily suggest using a ribbon cable model such as this (I haven’t tested that particular vendor, the one I used is gone, this is just an example): https://fr.aliexpress.com/item/1005005989694443.html

    Ribbon cable models have all the parts premounted, you just need to solder it in place which is hard enough. It’s also unclear to me how the emmc stuff happens without a ribbon cable.

    Other things I bought according to my AliExpress history:

    • a set of switch opening tools and screwdrivers
    • flux
    • kapton tape (I wrapped the chip in it entirely)
    • fine tweezers
    • a better soldering station
    • solder wick
