Building a Custom Pathfinder Fidget Toy
So this project is about making something clean, cool, and something Im going to use for a long time. It uses a PCB, a XIAO RP2040, Two Blue Leds, Two Green Leds, Two 120 ohm Resistors for the Green Leds, and Two 22 ohm Resistors for the Blue Ledss
So I did the project so that I could learn how to build something quick, cool, nice, and something I would actual use unlike the Blueprint Projects: Custom Hackpad and RP2040 DevBoard. I also did this project because I was bored and the image generator for the other project was out of credits.ts.

|---|---|---|---|---|---|
| PCB | To connect everything together | 1 | 5.31 | JLCPCB | |
| 10 of 120 ohm resistor for the green leds | To make it so that its safe for the XIAO RP2040, Also got 10 instead of 2 because it was cheaper | 1 | 0.26 | https://www.digikey.com/en/products/detail/stackpole-electronics-inc/CF14JT120R/1741278 | Digikey |
| 4 of 22 ohm resistor for the blue leds | To make it so that its safe for the XIAO RP2040, Also got 2 extra just in case I mess something up | 1 | 0.69 | https://www.digikey.com/en/products/detail/yageo/PNP1WVFTF52-22R/4135164 | Digikey |
| 2 blue leds | To show color | 1 | 1.18 | https://www.digikey.com/en/products/detail/qt-brightek-qtb/QBL8IB60D/9354289 | Digikey |
