STM32F4DISCOVERY extension board

This set of four boards (STM32F4DIS-EXT) expands the functionality of the STM32F4 Discovery kit. A base board connected to the STM32F4 Discovery kit provides a microSD card slot, Ethernet connectivity, extension connectors for LCD and camera boards as well as an easy access to UART, SPI, CAN and other interfaces. The Wi-Fi® board connects to the STM32F4 Discovery kit using a serial host interface (UART or SPI). A digital camera board featuring a 1.3-Megapixel CMOS sensor and a 3"5 LCD board with touch-screen capability, connected to the base board along with a Wi-Fi® board featuring the SN8200 Wi-Fi® module, form a complete system.
