In addition, the board also offers onboard 12x8 LED matrix, Qwiic connectors, VRTC and OFF pins, catering to all potential needs for your next project.
With R7FA4 PlUS B, you can easily upgrade your project and add wireless connectivity to extend the coverage of your current setup. If this is your first project, the board has everything you need to spark your creativity.
Features
- Based on R7FA4M1AB3CFM, and is compatible with Arduino UNO R4 WiFi.
- Utilizes Renesas Electronics' RA4M1 (Arm® Cortex®-M4) microcontroller, with a main frequency of 48MHz.
- Onboard ESP32-S3 module, integrates 2.4GHz Wi-Fi and Bluetooth LE dual-mode wireless communication, allowing the maker to use it for wireless communication. Combined with Arduino IoT Cloud, you can remotely monitor and control the projects.
- Onboard 12x8 red LED matrix, suitable for creative projects with animation or plotting sensor data, no additional hardware is required.
- Equipped with 256 kB Flash and 32 kB RAM, the expanded memory can easily handle complex projects.
- The R7FA4 Plus development board adds a 12-bit DAC, CAN bus and operational amplifiers, providing expanded functionality and flexibility for designs.
- Onboard 5V/3.3V headers for easy voltage switching, allowing the use of more expansion modules.
- Flexible power options, supporting USB-C power supply or external input power VIN (6V<=VIN<=21V).
- Onboard power indicator (PWR), USER LED, serial port receive indicator (RX), and transmit indicator (TX), making it easy to monitor the working status of the development board.
- Onboard ICSP interface, can be used as an SPI interface.
- Supports user soldering of corresponding interface insertion into the experimental board.
