Open429Z-D is an STM32 development board designed for the ST official tool STM32F429I-DISCO, which features the STM32F429ZIT6 microcontroller onboard.
The Open429Z-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 STM32 series microcontrollers.
What's on the mother board
- STM32F429I-DISCO socket: for easily connecting the STM32F429I-DISCO
- MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
- USB connector: USB to UART via the onboard convertor PL2303
- I2C1/I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
- I2S2/I2S3/I2C1 interface: easily connects to I2S peripherals such as audio module, etc.
- DCMI interface: for connecting camera
- SDIO interface: for connecting Micro SD module, features much faster access speed rather than SPI
- CAN1 interface: communicates with accessory boards which feature the CAN device conveniently
- CAN2 interface: communicates with accessory boards which feature the CAN device conveniently
- UART3 interface: easily connects to RS232, RS485, USB TO 232, etc.
SPI1/SPI4 + AD/DA interfaces:
- easily connects to SPI peripherals such as DataFlash (AT45DBxx), SD card, MP3 module, etc.
- easily connects to AD/DA modules (SPI1 features AD/DA alternative function)
- UART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
- 8-bit FMC interface: easily connects to peripherals such as NandFlash
- SAI1 interface: for connecting audio modules like UDA1380 module
- ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
- 5V DC jack
- 5V/3.3V power input/output: usually used as power output, also common-grounding with other user board
- JTAG/SWD interface: for debugging/programming
- 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
- USB to UART jumper
- AMS1117-3.3: 3.3V voltage regulator
- PL2303: USB to UART convertor
- 5V DC power switch
- Power indicator
- UART1 indicator
- Joystick: five positions
