Knurling Test Adapter

Note: Add picture or render of the breakout board

This is intended to be used as part of Hardware in the Loop testing. The idea is the ability to write host-based "integration tests" that exercise the behavior of a Unit Under Test (UUT) by mocking the outside world, or serving as a data Sink or Source for instrumentation commands or logging.

See HIL Testing Theory for more design and concept details.

It is currently a breakout board for the [Black Pill], based on the STM32F411. The breakout board adds:

• Dual RS-485 channels
• RJ-45 connectors for daisy-chaining power and RS-485
• A WS2812B LED for status
• PMOD breakouts for:
  • GPIO
  • I2C
  • SPI
  • UARTs

In the future, the hope is to donate this project to the Knurling-rs project.
