Overview

Open429Z-D is an STM32 development board designed for the ST official tool 32F429IDISCOVERY, 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

1. 32F429IDISCOVERY socket: for easily connecting the 32F429IDISCOVERY
2. MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
3. USB connector: USB to UART via the onboard convertor PL2303
4. I2C1/I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
5. I2S2/I2S3/I2C1 interface: easily connects to I2S peripherals such as audio module, etc.
6. DCMI interface: for connecting camera
7. SDIO interface: for connecting Micro SD module, features much faster access speed rather than SPI
8. CAN1 interface: communicates with accessory boards which feature the CAN device conveniently
9. CAN2 interface: communicates with accessory boards which feature the CAN device conveniently
10. UART3 interface: easily connects to RS232, RS485, USB TO 232, etc.
11. 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)
12. UART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
13. 8-bit FMC interface: easily connects to peripherals such as NandFlash
14. SAI1 interface: for connecting audio modules like UDA1380 module
15. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
16. 5V DC jack
17. 5V/3.3V power input/output: usually used as power output, also common-grounding with other user board
18. JTAG/SWD interface: for debugging/programming
19. 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
20. Boot mode switch: for configuring BOOT0 pin
21. USB to UART jumper
22. AMS1117-3.3: 3.3V voltage regulator
23. PL2303: USB to UART convertor
24. 12MHz crystal
25. 5V DC power switch
26. Power indicator
27. UART1 indicator
28. Joystick: five positions
