STM32F407VGT6 chip has 168MHz frequency, 1 Mbyte of Flash memory, 192K + 4K bytes of general-purpose SRAM, integrated Ethernet controller, USB 2.0 (OTG, Host, Device), 83 General purpose I/O pins, 12×16-bit and 2×32-bit timers, 3×12-bit A/D (24 channels), 2×12-bit D/A , 4xUSARTs, 2xUARTs, Real time clock (RTC), 2xI2C, 3xSPI and 2xCAN controllers.
25MHz crystal oscillator. We carefully chose the most convenient crystal value that provides clock frequency which can be used directly, or with the PLL multipliers to create higher MCU clock value. MCU card also contains 32.768 kHz crystal oscillator which provides external clock for RTCC module.
USB communications lines. These two jumpers, when in USB position, connect D+ and D- lines of the on-board USB connector with PA11 and PA12 microcontroller pins. Since STM32F407VGT6 supports USB, jumpers are in USB position.
Ethernet transceiver. MCU card contains single-chip Ethernet physical (PHY) layer transceiver which provides additional Ethernet functionality to STM32F407VGT6 controller.
