driving stepper-motors

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

Hi Stefan,
Thank you for your contact.
Could you please help check the SKU. No.?
