STM32 Development Board Designed For STM32F746I, Features The STM32F746IGT6 MCU, And Integrates Various Standard Interfaces, Pretty Easy For Peripheral Expansions.
Overview
Open746I-C is an STM32 development board designed for the STM32F746IGT6 microcontroller, consists of the mother board and the MCU core board Core746I.
The Open746I-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
- MCU core board connector: for easily connecting the Core746I
- Arduino interface: for connecting Arduino shields
- DCMI interface: for connecting camera
- 8-bit FMC interface: easily connects to peripherals such as NandFlash
- ULPI interface: for connecting high-speed USB peripheral (the STM32F746I integrates USB HS controller without any PHY device)
- LCD interface 1: for connecting 10.1inch LCD, 7inch LCD
- LCD interface 2: for connecting 4.3inch LCD
- SAI1 interface: for connecting audio modules
- ICSP interface: Arduino ICSP
- SPI1/SPI2 interfaces:
- easily connects to SPI peripherals such as DataFlash (AT45DBxx, W25QXX), SD card, MP3 module, etc.
- easily connects to AD/DA modules (SPI1 features AD/DA alternative function)
- Ethernet interface: for connecting Ethernet modules
- I2S2/I2S3/I2C1 interface: easily connects to I2S peripherals such as audio module, etc.
- USART1 connector: USB to UASRT via the onboard convertor CP2102
- QUADSPI interface: 4-wires SPI interface (the F7 series latest peripheral interface), for connecting serial Flash modules like W25QXX Board
- SDMMC interface: for connecting Micro SD module, features much faster access speed rather than SPI
- USART3 interface: easily connects to RS232, RS485, USB TO 232, etc.
- CAN2 interface: for connecting CAN modules
- CAN1 interface: for connecting CAN modules
- I2C1/I2C4 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), EEPROM (AT24Cxx), 10 DOF IMU Sensor, etc.
- MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
- 5V DC jack
- 5V/3.3V power input/output: usually used as power output, also common-grounding with other user board
- Power supply switch: powered from 5VDC OR USB connection of the USART1
- CP2102: USB to UART convertor
- LEDs: convenient for indicating I/O status and/or program running state
- Joystick: five positions
- WAKE UP button: used as regular button, and/or wake up the STM32 MCU from sleep
- Reset button
- USART1 jumper
- 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
- KEY 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
- Arduino jumper
- short the upper pins, A4, A5 is used as AD function
- short the lower pins, A4, A5 is used as I2C function
