The Waveshare R7FA4 PLUS A Enhanced Arduino-Compatible Development Board is an advanced version of the Arduino UNO R4 Minima, designed to cater to the needs of developers and hobbyists alike. This board is built around the R7FA4 microcontroller, which is a 32-bit ARM Cortex-M4 processor, ensuring robust performance with a clock frequency of 48 MHz. It boasts a substantial storage capacity with 256 kB of Flash memory and 32 kB of RAM.
The development board offers a variety of power options, including an operating voltage that supports both 5V and 3.3V, making it compatible with a wider range of shields. The power input can handle a range from 6V to 24V. A lateral reset button has been thoughtfully positioned to facilitate ease of use when shields are connected.
For connectivity and interfacing, the board is equipped with 14 digital pins, 6 analog pins, 2 DAC outputs, and 6 PWM channels. It also includes interfaces for UART, I2C, SPI, and CAN, allowing for versatile communication and peripheral connections. The low-profile DC jack is designed to prevent obstruction of shields during connection.
The board features a power output header that provides either 5V or 3.3V power output, ensuring compatibility and common-grounding with other boards. The 5V power output is capable of delivering up to 2000 mA, offering higher driving capability for connected devices. Additionally, the board supports experimental boards with a solder pad provided for DIY interfaces, enhancing its utility for custom projects.
Onboard components include an R7FA4M1AB3CFM microcontroller, AMS1117-3.3V voltage regulator, MP8759 5V voltage regulator, and a USB Type-C connector for program uploading or serial port debugging. The board also features a power configuration switch, SWD indicator, power indicator, user LED, and serial port RX/TX indicators. The pinout definition and outline dimensions are clearly defined, ensuring straightforward integration into projects.
Please note that the Waveshare R7FA4 PLUS A Enhanced Arduino-Compatible Development Board should be handled with care, following all standard safety precautions for electronic devices.
