Open407V-D is an STM32 development board designed for the ST official tool STM32F4DISCOVERY, which features the STM32F407VGT6microcontroller onboard.
The Open407V-D supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32F4 series microcontrollers.
What's on the mother board
STM32F407VGT6 development board on board resource
STM32F4DISCOVERY socket: for easily connecting the STM32F4DISCOVERY
USART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
SPI1/SPI2 + AD/DA interface
easily connects to SPI peripherals such as DataFlash (AT45DBxx), SD card, MP3 module, etc.
SPI1 features AD/DA alternative function, supports connecting AD/DA module as well
CAN1 interface: communicates with accessory boards which feature the CAN device conveniently
CAN2 interface: communicates with accessory boards which feature the CAN device conveniently
I2C1/I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
I2S2 / I2S3 / I2C1: for connecting I2S peripherals, such as Audio module
DCMI interface: for connecting camera module
SDIO interface: for connecting Micro SD module, features much faster access speed rather than SPI
FSMC + SPI interface (16-bit FSMC + SPI): for connecting touch screen LCD
FSMC interface (8-bit FSMC): easily connects to peripherals such as NandFlash, Ethernet, etc.
USART3 interface: easily connects to RS232, RS485, USB TO 232, etc.
ULPI interface: for connecting high-speed USB peripheral (the STM32F407V integrates USB HS controller without any PHY device)
Ethernet interface: easily connects the MCU to ethernet network by using an additional ethernet module
5V DC jack
5V/3.3 V power input/output: usually used as power output, also common-grounding with other user board
MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
JTAG/SWD interface: for debugging/programming
SD Card Detect jumper
Joystick jumper
short the jumper to connect the joystick to default I/Os used in example code
open the jumper to connect the joystick to custom I/Os via jumper wires
Boot mode switch: for configuring BOOT0 pin
LCD backlight adjustment enable jumper
short the jumper to enable LCD backlight adjustment
open the jumper to disable, and set free the I/O port
AMS1117-3.3: 3.3V voltage regulator
Power supply switch: 5V DC on/off switch
Power indicator
Joystick: five positions
