1 × ATTiny1616-MNR QFN-16 https://www.digikey.com/en/products/detail/microchip-technology/ATTINY1616-MNR/7354618
12 × TVS Diodes-5V 0402 Sorry, 0603's would be easier to solder, but you're gonna want tweezers
12 × Protective Resistors-47Ohm to 330Ohm 0402 You can use any value you want, just assume someone's gonna pour coffee on your machine and it'll need to handle that.
