  • Need help with name of component (Naked USB Flash drive?)

    1) Get https://www.adafruit.com/product/3500 Instantly start controlling built-in RGB LED, and LED strips with basically no programming. 2) Stop playing with Python, that won't get you anywhere close to where you want. Switch over to Arduino and learn C++. 3) Understand the bootloader code https://github.com/Microsoft/uf2-samdx1 - then write an app to allow R/W blocks on built-in flash, while also playing with LEDs. 4) Since it only has 256K flash, you'll need to hook up some flash chips if you want more space. (Too many types to list, depends on your cost vs speed trade-offs.)
