Product Description
STM32 Development Board Designed For STM32F205R Series, Features The STM32F205RBT6 MCU, And Integrates Various Standard Interfaces, Pretty Easy For Peripheral Expansions.
Overview
Open205R-C is an STM32 development board designed for the STM32F205RBT6 microcontroller, consists of the mother board and the MCU core board Core205R.
The Open205R-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 STM32F2 series microcontrollers.
What's on the mother board
- MCU core board connector: for easily connecting the Core205R
- UART3 interface: easily connects to RS232, USB TO 232, etc.
- 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
- I2C1/I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
- SPI1/SPI2 + AD/DA interface
- easily connects to SPI peripherals such as DataFlash (AT45DBxx), SD card, MP3 module, etc.
- SPI1 features AD/DA alternative function, supports connecting AD/DA module as well
- USART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
- LCD interface: for connecting touch screen LCD
- ULPI interface: for connecting high-speed USB peripheral (the STM32F205R integrates USB HS controller without any PHY device)
- UART1 interface: easily connects to RS232, USB TO 232, etc.
- CAN2 interface: communicates with accessory boards which feature the CAN device conveniently
- CAN1 interface: communicates with accessory boards which feature the CAN device conveniently
- 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/3.3 V power input/output: usually used as power output, also common-grounding with other user board
- MCU pins connector: VCC, GND, and all the I/O ports are accessible on expansion connectors for further expansion
- LEDs 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
- 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
- User key/Wake-Up button 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
- 5V power selection jumper: powered from Core 5V or 5V DC
- 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: convenient for I/O input (five positions)
