STM3210E-EVAL评估板

The STM3210E-EVAL evaluation board is designed as a complete development platform for STMicroelectronic’s ARM Cortex-M3 core-based STM32F103ZGT6 microcontroller with full speed USB2.0, CAN2.0A/B compliant interface, two I2S channels, two I2C channels, five USART channels with smartcard support, three SPI channels, two DAC channels, FSMC interface, SDIO, internal 96 KB SRAM and 1 MB Flash, JTAG and SWD debug support.

The STM3210E-EVAL products delivered with the MB672 board versions D-03 or older are based on the STM32F103ZET6 instead of the STM32F103ZGT6 and include 64 KB internal SRAM and 512 KB Flash. The board number and version are on a label on the bottom side of the board.

The full range of hardware features on the board helps you to evaluate all peripherals (USB, motor control, CAN, MicroSD Card, smartcard, USART, NOR Flash, NAND Flash, SRAM) and develop your own applications. Extension headers make it easy to connect a daughterboard or wrapping board for your specific application.
