Open429I-C Package A, STM32F4 Development Board

Overview

Open429I-C is an STM32 development board designed for the STM32F429IGT6 microcontroller, consists of the mother board and the MCU core boardCore429I.

The Open429I-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 STM32 series microcontrollers.

What's on the mother board

21. MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
22. PL2303: USB to UART convertor
23. LEDs: convenient for indicating I/O status and/or program running state
24. PL2303 TX-LED / RX-LED
25. 12MHz crystal: for PL2303
26. Joystick: five positions
27. WAKE UP button: used as regular button, and/or wake up the STM32 MCU from sleep
28. USB to UART jumper
29. LED jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
30. Button/Joystick jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
