Trinamical stepper breakout with TMC2209

About two weeks ago, we designed a breakout for the A4988 (https://blog.adafruit.com/2024/11/11/the-a4988-is-a-classic-stepper-driver-in-a-new-fit/), and we're still waiting for those prototype PCBs, but we're not one to wait, because we think that the idea is a good one...so why not design another version? This time with the Trinamic TMC2209 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC2209-LA-T/10232491). This is a similar "Step & Dir" type driver, with a wide motor range of 4.75 – 28 Volts and separate 3~5V IO pin.
