Open407Z-C is an STM32 development board designed for the STM32F407ZxT6 microcontroller, consists of the mother board and the MCU core boardCore407Z.
The Open407Z-C 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
- MCU core board connector: for easily connecting the MCU core board
- ULPI interface: for connecting high-speed USB peripheral (the STM32F407Z integrates USB HS controller without any PHY device)
- 16-bit FSMC + SPI interface: for connecting touch screen LCD
- 8-bit FSMC interface: easily connects to peripherals such as NandFlash, Ethernet, etc.
SPI1 / SPI2 + AD / DA interface
- for connecting SPI peripherals such as DataFlash (AT45DBxx), SD card, MP3 module, etc.
- for connecting AD/DA module as well, thanks to the SPI1 AD/DA alternative function
- SDIO interface: for connecting Micro SD module, features much faster access speed rather than SPI
- I2S2 / I2S3 / I2C1: for connecting I2S peripherals, such as Audio module
- USART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
- CAN1 interface: for connecting CAN module
- CAN2 interface: for connecting CAN module
- I2C1 / I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
- DCMI interface: for connecting camera module
- UART3 interface: easily connects to RS232, USB TO 232, etc.
- Ethernet interface: easily connects the MCU to ethernet network by using an additional ethernet module
- ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
- PS/2 interface: easily connects to PS/2 keyboard and/or mouse
- 16-bit FSMC interface: easily connects to peripherals such as NorFlash, SRAM, etc.
- 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 I/O ports are accessible on expansion connectors for further expansion
- 5VDC: powered from 5V DC jack
- Core5V: powered from the MCU core board
- LEDs jumper
- User key / Wake-Up button jumper
- Joystick jumper
- PS/2 jumper
- LEDs: convenient for indicating I/O status and/or program running state
- User key: convenient for I/O input and/or interact with running code
- Wake-Up button: wake up the STM32 MCU from sleep mode, also used as regular user key
- Joystick: five positions
