Offers customizable I/O port access with expansion connectors
The Waveshare Core407I STM32F4 Core Board is a compact development platform featuring the STM32F407IGT6 microcontroller, designed for initiating application development within the STM32F family. This board integrates essential components such as a USB communication interface, JTAG/SWD programming and debugging interface, clock circuit, and USB power management. It also includes a boot mode selection feature, making it a comprehensive, ready-to-run system.
The board is equipped with pin headers on the backside, allowing it to be easily integrated into application boards, serving as the MCU core circuit. All input/output ports are accessible via these pin headers, which are designed with a 2.0mm pitch to minimize PCB size. The STM32F407IGT6 microcontroller offers high performance with a Cortex-M4 32-bit RISC core, operating at a frequency of 168MHz. It supports a wide range of communication interfaces, including SPI, USART, UART, I2S, I2C, FSMC, SDIO, CAN, USB 2.0, and Ethernet MAC.
Additional features include AD and DA converters, a power supply switch, a boot mode switch, power indicators, and a reset button. The board also supports USB communication as both a device and a host, with the capability to connect to USB devices via an OTG cable. Expansion connectors provide access to all I/O ports, VCC, and GND, facilitating further development and customization.
