Raspberry Pi Pico Development Board & Future Controller

The RP2 Dev-Board allows you to quickly create programs with buttons and LEDs already wired up for you. The boards/PCBs are great quality but they seem to be easily scratched, hopefully that wont disconnect the circuits and wires inside the PCB. When soldering, sometimes they create some kind of black glossy glass (Which I assume is lead from the solder) onto the PCB which requires to be scraped off to be removed. Other than that it is great quality, easy to solder onto and has no short-circuits. I recommend PCBWay to other friends that would also like to make their own PCBs. Unfortunately I did not buy the right buttons which means they aren’t the same size. This means I have to buy the correct size and the project will be on hold for a while. This is also my first time soldering so the solder quality isn’t that great, sorry about that.
