Ahh we are trying to finish some older projects off, this week we put together a KB2040 which we designed earlier this year It's the same size and pinout as a Pro Micro - for use with keyboard projects like this DIY one https://1upkeyboards.com/shop/keyboard-kits/macro-pads/sweet16-macro-pad-white/ We generated a pinout diagram to help us verify the muxing is all right, and we'll maybe try to get it in pink!
The Great Search - Current Sense Resistors
https://www.digikey.com/short/djch7b70
For the STSPIN stepper breakout board, we need some current sense/limiting resistors. These are special resistors that are very low resistance but very high wattage, so they can dissipate the heat from the Resistance * Current^2. One thing we need to optimize for in this project is space over price - since the board size is fixed. So let's find the smallest current sense resistor we can, we might discover some interesting things!
