Main Content

Cheetah is a DC motor driver board; which is interfaced using GPIO and SPI. The board has a L9958 DC motor driver chip, which is a SPI controlled H-Bridge designed for the control of DC motors under extreme condition. The H-Bridge is protected from short circuit and overheating. The board also has a 32-bit quadrature counter for quadrature encoder feedback. The quadrature counter also interfaces with incremental encoders to perform a variety of marker functions. 


  • On-board 32 bit quadrature encoder for speed and position feedback chip
  • Operating frequency of L9958 is up to 20 kHz
  • Overheating and short circuit protection
  • Open load detection in on condition
  • Enable and disable input
  • SPI for configuration
  • X1, X2 or X4 mode of quadrature counting
