  * Consult the [X-NUCLEO-IHM03A1 user manual](https://www.st.com/resource/en/user_manual/dm00206777-getting-started-with-the-high-power-stepper-motor-driver-expansion-board-based-on-powerstep01-for-stm32-nucleo-stmicroelectronics.pdf) for information about how to stack the boards. A brief overview of the process follows, but read the manual first.
  * Make the same motor connector doodad for the second board and install it. Also prepare two short red and black power wires to piggy-back the motor power input.
  * You will need to move some resistors. The manual link above will list which ones.
