Be careful :
My electrical test actually show : (small level shifter and MCP23017 at the top right of the picture)
1 / For red driver ZS-X11H V1 the level shifter is not needed,PWM work at 3.3V and brake also, so you can use the EN pin like in PCB V1.01 to brake and simply some minor change in the code can mange this feature.
2 / using level shifter invert the signal (maybe not the TSX0108E) , so on startup or code upload motor can run at full PWM and it's very dangerous.
3 / MCP23017 work well for blinking led ,manage the motor Dir but fail to command the brake on motor driver (I don't understand why).
Here the component i have not tested:
-Black BL driver.
-Other Red Driver ZS-X11H but the V2 version !!
-8 pin level shifter from marotronics
-TSX0108E level shifter
