Seeeduino V4.2 is an Arduino-compatible board, which is based on ATmga328P MCU just like the Arduino Uno R3. As Arduino is opensource hardware, that’s why there are so many Arduinos and Arduino-compatible boards in the world, and among them Seeeduino V4.2 is one of the best Arduinos, Seeeduino V4.2 is much more stable, easy-to-use and even good looking. And you don’t need an expensive type USB cable, you could simply use your phone micro-USB cable to power and program this Arduino board.
Seeeduino V4.2 is based the Arduino UNO bootloader, and with an ATMEGA16U2 as a Uart-to-USB converter, which means that the board can basically work like a FTDI chip. You can program the board via a micro-USB cable, if you have an Android phone, you won’t need to buy an expensive type USB cable, you can use your phone USB cable to power and program this Arduino board. Also you can power the board via a DC Jack input, 7 to 15V is acceptable. There’s a switch to choose the system supply voltage, 3.3V or 5V, which is very useful if you want to set the system to 3.3V to save power.
Finally, the three on-board Grove interface can make your board connect to Groves easily. Want to make something awesome, maybe just a Seeeduino V4.2 and some Groves is enough.
If you are not familiar with Grove interface (especially beginners), please read this document: Introduction to Grove before using this product.

The images below show an overview of Seeeduino v4.2 hardware features. The pin-out and alternate functions of various pins of Seeeduino v4.2 are shown in the pin-out diagram. This could be used as a quick reference.
- ❶ USB Input: USB Port is used to connect the board to your PC for programming and for powering up.
- ❷ DC Input: The DC power jack allows your Seeeduino board to be powered from a wall adapter so that you can supply more power to your project if needed. For example, when using DC motors or other high power devices. The DC input can be 7V-15V.
- ❸ Grove Connectors: SeeedStudio has a variety of sensors/devices that can make use of this I2C or UART connection. In addition, we sell independent Grove connectors to help you make our own sensor connections. The I2C Grove connector is also connected to analog pin A4 and A5 for SDA and SCL respectively if you would like to use those pins instead. The UART Grove connector is connected to digital pins 0 and 1 for RX and TX respectively.
- ❹ ICSP: This is the ICSP connection for the ATmega328P, it is located in the standard ICSP/SPI position for Arduino Uno, Due, Mega, and Leonardo compatible hardware (e.g. shields) that may use this connector. The SPI pins in this port: MISO, SCK, and MOSI, are also connected to digital pins 12, 13, and 11 respectively just like those of the Arduino Uno.
- ❺ USB 2 Uart: Pinout of USB-2-Uart. These pads can be used to interact with other UART devices by putting the on-board ATmega328 in reset mode. This makes Seeeduino V4.2 to be used a USB2UART utility board.
- ❻ System Power Switch: Slide switch is used to change the logic level and operating voltage of the board to either 5V or 3.3V.
- ❼ Reset: This button is conveniently placed on the side to allow you to reset the Seeeduino board even when a shield is placed on top. This is not the case in other Arduino boards where the button is placed on top making it hard to access.
- ❽ LED-D13: The LED is connected to D13 pin of the board. This can be used as an on-board LED indicator for programs/sketches.
- ❾ RX/TX Indicator: The TX and RX LED indicators are connected to TX and RX of USB-to-UART chip. They work automatically, they let you know when the board is sending or receiving data respectively.
- Step 1. Prepare a Seeeduino V4.2 and a Micro-USB cable.
- Step 2. Connect the Seeeduino V4.2 to your computer with the Micro-USB Cable. Then the green power LED (labeled PWR) should go on.
Caution: Please plug the USB cable gently, otherwise you may damage the interface.Please use the USB cable with 4 wires inside, the 2 wires cable can’t transfer data. If you are not sure about the wire you have, you can click here to buy one.
If you have already installed Arduino Software on your computer, it will detect automatically this Seeeduino V4.2. board, no need to install new drivers. But if it fails to install drivers or it’s your first time, please install the drivers first.
This drive is available for Windows XP, Windows Vista, Windows 7, Windows 8/8.1 and Windows 10. Click below to download the drivers:
- Plug in your board and wait for Windows to begin its driver installation process. After a few moments, the process will fail, despite best efforts.
- Click on the Start Menu, and open up the Control Panel.
- While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
- Look under Ports (COM & LPT). You should find an open port named “Seeeduino v4.2”. If there is no COM & LPT section, look under “Other Devices” for “Unknown Device”.
- Right click on the “Seeeduino v4.2” port and choose the “Update Driver Software” option.
- Next, choose the “Browse my computer for Driver software” option.
- Finally, navigate to and select the driver file named “seeed_usb_serial.inf”
- Windows will finish up the driver installation from there.
For Mac OSX and Linux
You don’t need to install any drivers.
And the rest is like a normal Arduino UNO board in terms of software and programming.
