Seeeduino V4.2 is an Arduino-compatible board, which is based on ATmga328P MCU. There're so many Arduinos and Arduino-compatible boards in the world, and we think that Seeeduino V4.2 is one of the best Arduinos, Seeeduino V4.2 is much more stable, easy-to-use and even good looking.

Seeeduino V4.2 is based on the Arduino UNO bootloader, and with an ATMEGA16U2 as a UART-to-USB converter, which means that the board can basically work like an FTDI chip. You can program the board via a micro-USB cable, if you have an Android phone, you can find a micro-USB cable easily. 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.

Attention

Operating the chip at 16 MHz with 3.3 volts is beyond the specified maximum frequency "Safe Operating Area" for the ATmga328P chip. So when you switch the working voltage to 3.3V, it may not be safe. However, at room temperature, most chips work fine that way.

Features

  • ATmega328P microcontroller

  • Arduino UNO bootloader

  • 14 Digital I/O Pins (6 PWM outputs)

  • 6 Analog Inputs

    Hello,
    this is a well done design for an Arduino.
    Reset switch at the side and 5V / 3.3V data voltage switches are really helpfull.
    A special USB driver works after some tries. Here is a description in German for the USB.

    Unlike other Arduino Uno boards, this one requires loading drivers before it can be recognized. Other than this the board works perfectly well.

    Received two of them today. They are very nice looking board. I've not had a chance to actually test them out yet but so far so good.

    The board is not correctly detected (Windows 7 and Windows 10) : just seen as a AtMega DFU. The product is not usable.

    It looked ok on arrival. There is a red marking on the ATmega16u2.
    But it does not work (both of them); neither the ATmega16u2 nor the Atmega328p have been programmed (no USB for download, no boot loader).
    After programming both chips program upload is still impossible.
    Please send checked replacements!

    I really like this board. Especially the two I2C grove connectors. The only improvements would be to have a faster processor, more memory, and a more durable USB connector than the micro which doesn't handle the power requirements very well. I would like to see solder points for connecting a cable to the board directly when the USB connector fails, so the board is still usable.

    I have had 2 of these boards running 24/7 on my desk since receiving them over a month ago, and have noticed no issues with heating or "oddness". My only problem with them is keeping my very curious kitten away from them for any length of time; still, they have even survived her playful attacks.

    All-in-all, these represent an excellent value for my prototyping needs at the '328p end of the spectrum.
