Open205R-C platforma rozwojowa z STM32F205RBT6

Open205R-C platforma rozwojowa przeznaczona do pracy z mikrokontrolerem STM32F205RBT6, składająca się z płyty bazowej oraz modułu CORE205R. Liczne złącza dodatkowe umożliwiają łatwą rozbudowę platformy o dodatkowe moduły rozszerzeń np. wyświetlacze, moduły komunikacyjne UART, CAN itp.

Opis płyty bazowej:

* 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)
