It sports a newer microcontroller, but still has the same bootloader and pinout. The best part? It costs less than four dollars.

One can use serial programming, with genuine STM32 MCUs, Single Wire Debug (SWD) via the four-pin break-out header, or the USB port if a suitable bootloader is installed.

Applicable six-step motor-control algorithms for sensored or sensorless BLDC motor control are available as part of a set of hardware, software, and firmware tools for product development.

Express Logic has integrated the STMicroelectronics’ Secure Boot and Secure Firmware Update v.2.0 services with its X-Ware IoT Platform for its developers using the STM32-family of ARM Cortex-M ...
