Schematic design //Things to drag and drop from minimal schematic (or just take the minimal schematic and pare things down until I have something I want - flash - USB power (how much do I need this) //Things to add //RTC - finishing RTC (test connecting to i2c with adafruit breakout to pi pico) //LEDS - SMD LEDS - switching configuration - look into what rgb led needs and if going straight from gpio is viable //POWER - how do i deal with eurorack power source? - esp how do I deal with the small connector 12v and -12v - where do I feed the rp2040 the 5V - thinking I can just slot it into where the USB power would be? probably a place to add in power right to the chip - if its actually 12V do I need a level shifter? maybe a 12v right to 3.3v or something? implementing polyfuse protection circuit //INPUT HANDLING - using Schotty barriers like the hagiwo stuff? maybe research this a bit more? david seemed to think that would be ok //OUTPUT HANDLING implementing david's circuit for output
