Hacking Flex cable for RP2040 OR board with inbuilt resistors?

[Fatfingers]

Hey!

Just putting the finishing touches on my first picofly and overall the only real pia experienced in the process was the resistors on the RP2040. The resistors just didn’t like my 38awg wire being soldered to it and it was super annoying when occasionally I would desolder the other end of the resistor that was soldered to the board. Was wondering if anyone is working on or has created a flex cable for the RP2040 which has the 48ohm resistor in the flex and nice juicy pads for my wires to solder to? Or Better yet a 2040 board with resistors already attached?

the Waveshare rp2040-tiny has built in resistor

Oh wow if that’s actually the case that is mad. When I look into the item on its web page it says based off of the RP 2040 but doesn’t mention anything about what is actually different. I can see what looks to be like resistors on the board but is there anywhere I can read into this chip in reguards to how people have used it for the picofly mod and if they ran into any issues?

Care to elaborate on this? I believe the resistors the OP is talking about are the 47 ohm for the emmc data lines.

Supposedly it has these resistors:
