The STM32 series of 32-bit microcontrollers are based on the Cortex-M processor, which can support a wide range of 32-bit applications, including high performance, real-time functions, digital signal processing, and low power consumption and low voltage operation. Its core based on industry standards, supported by a large number of tools and software, makes this series of chips an ideal choice for many products.
The following development board combinations all support the operation of the host computer software Image to EPD. The Image to EPD software supports the direct import of pictures, eliminating the trouble of picture production and bitmap convert. The relevant download information is as follows:
