Based on STM32CUBEMX drive low-voltage stepper motor driver STSPIN220----1. Kit overview
Kit overview
STM32C011F4Px_STSPIN220 is a low-voltage stepper motor driver kit based on STM32C011F4Px. Among them, the STSPIN220 is a stepper motor driver integrating control logic and a low RDS (turn on) power stage in a small VFQFPN 3 x 3 x 1.0 mm package. The kit provides a full suite of protection features, including over-current, over-temperature, and short-circuit protection, and can be forced into a zero-drain state to significantly extend battery life.
Recently, I am taking ST courses. If you need samples, you can add qun application: 615061293.

Function diagram
Figure 1 shows the front view of the STM32C011F4Px_STSPIN220 evaluation kit.
Figure 2 shows the rear view of the STM32C011F4Px_STSPIN220 evaluation kit.
System Block Diagram
As shown in Figure 3, it is the system block diagram of the STM32C011F4Px_STSPIN220 development board.
jumper setting
- Use the jumper cap to change the mode of BOOT0, and set the BOOT pin to determine the boot mode of the STM32 MCU.
The way to start it is as follows:
- BOOT Boot from user Flash
- BOOT Boot from system memory
- BOOT Boot from SRAM
- Use a jumper cap to power the STSPIN220 and connect Vs to VIN.
