Hi,

your microbit driver-extension-board uses H-bridges to be able to drive brushed DC-motors AND steppermotors.

For steppermotors there are driver-chips like the 8825 which have a step/dir-interface. Do you plan to put a stepper-motor-driver-board on the market in the near future?

If not did you puplish the internal code (that's hidden under the hood) of the makecode-blocks for the driver-board?

Another question:
The makecode-blocks have parameters for the motor rotation-direction CW/CCW, degrees or revolutions but there seems to be no parameter for speed. Is this correct?

best regards

Stefan
