ENSYS SToRM32 V3.3 Board (Beta)


Out of stock

This SToRM32 3.3 Board is compatible with OlliW SToRM32 3.3 Design and v3.3 Firmware. 

This board has no motor drivers; NT motor modules need thus be used.

Main differences to OlliW design:

  • NT ant NT-X conntectors are 1.25mm Molex Picoblade. 4 pin and 7 pin respectively. This is due to better part sourcing availablility.
  • Slightly different 2.54mm pinout.
  • CH340 USB-Serial IC instead of Silabs IC.
  • Added reverse polarity protection.
  • Lower max input voltage (17V instead of 27V)
