A board to convert single-ended SPI signals (SCLK, MOSI, MISO, CS) from an ODrive to differential pairs adhering to Low-Voltage Differential Signaling standard (LVDS),

 

The advantages to differential signals versus single-ended signals:

  • Environmental noise appears across both the + and - of the differential pair. Since the difference between + and - is taken, this common-mode noise is thus eliminated.

  • Similarly, noise that these signals destructively interfere.

  • Signal integrity and robustness is overall improved.

 

This connects to 2 SPI LVDS Slave Breakout boards, where it is then converted back to single-ended signals for the peripheral to properly receive.
