## Description

desertcart.com: KEYESTUDIO V4.0 Development Board for Arduino UNO R3 with USB Cable : Electronics

Review: Arduino Uno R3, on the cheap - Initially the Keyestudio board was not recognized on WIN10. After checking some of the reviews, and updating the CP2102 driver, it worked perfectly. Although the pin descriptions are written on the board, I would prefer if the pin descriptions were also written on the headers as well. All-in-all a great development board at a great price.
Review: Good Clone at a great price. - I saw this for $9 and figured why not. I figured worst case, I could at least use the 'Atmega328p' which run about $13 to $15 for two anyway. It works great! I ended up using it to prototype my design instead of my Arduino Mega and when I was done, I actually loaded it with the "Arduino as ISP" sketch and used it to flash two breadboarded AVRs. This comes nicely packaged, a box inside a box, and includes an 18" USB cable. I also think the Black/Yellow is a nice change from the usual blue or all black PCBs. The top layer screening isn't as good as the original Arduinos or more expensive clones but you can still read the lettering.

## Features

- KEYESTUDIO V4.0 board is updated with CP2102 USB serial chip, fully compatible with arduino.
- 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP headers and a reset button.
- This microcontroller can be used by connecting it to a computer with a USB cable or power it with an AC to DC adapter. Also, it comes with the USB cable.
- BEAUTIFUL LOOK & PACKAGING: cool yellow-black design which is a departure from the standard, dull, black boards, the yellow silk screen on black mask make it easy to read the pin labels
- Flash Memory: 32 KB (ATMEGA328P-PU) of which 0.5 KB used by bootloader

## Questions & Answers

**Q: Does it support jtag? Ejtag?**
A: Nope.  Not much JTAG support in the lower-end Arduino world.

**Q: What drivers do I need to install to get this to work?**
A: Install the open source Arduino Development Environment software on your computer. These board are 100% compatible with the standard Arduino UNO R3. You should be able to compile and upload your software to this board with no additional drivers being needed. Silicon Labs does have the USB to UART drivers available on their website just in case you run into an issue with the USB communications. This board worked just fine on my computer, but I already use Silicon Labs USB bridges for my other work. I may already have had their drivers installed so I did not see any issues.

**Q: where i can boy motor shield and Led dot matrix 8 * 16 for KS0470 model?**
A: Amazon.  Search “Arduino Uno Motor Shield”. Again Amazon and search “MAX7219”.

### ⭐⭐⭐⭐ Cheap and easy
*by N***O on January 19, 2026*

I bought this while ago great for testing and prototyping added it to my Mr.Cupcake from fnaf. 3D printed the shell added a servo shield and some servos BAHMM Awesome eye movement! granted the memory doesn't store a lot a movement as it is a micro processer but will do great as a cheat alternative!
