A raspberry pi/ESP32 project involving musical beat detection and stepper motors

ESP32s

I used the 38-pin ESP32 development boards available from A-Z Delivery https://az-delivery.com/products/esp32-developmentboard or Amazon https://www.amazon.com/AZDelivery-Nodemcu-CP2102-Module-Development/dp/B07H3TTCCW/

Silent Step Stick

This is the TMC2130 chip made by Trinamic. Info at https://www.trinamic.com/support/eval-kits/details/silentstepstick/. Note that you need the SPI version of the development board. Non-SPI ones look similar but need a next-to-impossible modification to enable SPI.
