A clear and concise description of what the failure / bug is. Describe the problem NOT the fix.

Short Summary of the expected behavior: Connect an SPI Controller to and SPI Peripheral should not damage parts.

Short Summary of the buggy behavior: 5V controllers for example UNO may over voltage inputs on 3.3V Peripherals for example ESP32

Elementary explanation of voltage incompatibility and some level shifting solutions.
