Designers who use the STM32F407 series of Arm® Cortex®-M4 core-based microcontrollers can evaluate the pin- and function-compatible Geehy Semiconductor replacement part, the APM32F407, using the APM32F407IG MINIBOARD.
The MINIBOARD supports the Windows operating system, and is compatible with the Keil MDK-ARM development environment.
It features a USB Type-B interface, a JTAG/SWD interface, 134 GPIOs, and a USART interface.
It also includes two LEDs, two user buttons, and one reset key.
