R7FA4 Plus B Development Board
Overview
R7FA4 PlUS B combines the processing power and the new peripherals of Renesas Electronics' RA4M1 microcontroller with wireless connectivity capabilities of Espressif's ESP32-S3. 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.

Good quality. Nice design
Size: 4 Panel, Color: Chocolate Brown
Love it. Beautiful and good material. Just a little bit too high for my room.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.

Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.

Works well
Size: 4 Panel, Color: Coal Black
i bought this for 3 reasons.
1. Privacy when changing so I don't have to lock dog out of room.
2. In case MIL comes over and wants to snoop. She won't be able to see my bedroom.
3. A nice backdrop to use when taking photos of the clothing I make.
This is perfect for me.
My only "complaint" is that it is not the most sturdy thing. I have to finagle it in a way that keeps it from falling over.
But for the price, it can't be beat!
