Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Plug a pico rpi into usb and code it. No electronics needed.
I thought the Schottky diode in the manual/psu diagram was built in, not you added it.
Next step put pico rpi on breadboard but can't wire so look for pcb but can't solder and don't know what caps and resistors are and colour blind and everything is too small to read the writing on anyway and what's a multimeter and does it have a capacitor range.
Wiring is not electronics, join gnd to gnd , + to +, clk to clk, data to data etc.
no electronics or even what clk or data is, just wire and code.
It was only when using adc it was mentioned the pico rpi board psu is noisy so then I changed the psu but don't think it was really needed.

This is the point. You can use the Pico / PicoMite simply by wiring. You don't need electronics knowledge to do the basics (although it's not a great idea to short outputs to either supply rail). The manual tells you the safe output limits, the approximate current consumption and shows what's onboard the Pico. Many people will never need anything else.
