100% of 100

Grove Shield for Seeeduino XIAO is a plug-and-play Grove extension board for Seeeduino XIAO. With the on-board battery management chip and battery bonding pad, you could easily power your Seeeduino XIAO with lithium battery and recharge it. 8 Grove connectors onboard includes two Grove IIC and one UART. It acts as a bridge for Seeeduino XIAO and Seeed's Grove system. Flash SPI bonding pad allows you add Flash to Seeeduino XIAO to expand its memory space, providing Seeeduino XIAO with more possibilities. 




  • On-board Lithium Battery Charging and Management Function
  • Grove connectors (Grove IIC*2, Grove UART*1), all 14 GPIO led out
  • Compact and Breakable Design
  • SPI-Flash Bonding Pad Reserved
  • On-board Power Switch and Charging Status Indicator Light


Seeeduino XIAO has been becoming more and more popular in our community since it was released! As we have Grove Shield for many mainstream boards for easy test and better use of our Grove modules, many fans of Seeeduino XIAO have been asking whether we will have a Grove Shield for it, the much-anticipated Grove Shield for Seeeduino XIAO is now on board!

It’s a plug-and-play Grove extension board for Seeeduino XIAO. This Shield helps you get rid of jumper wires and soldering work by pulling out the pins of the Seeeduino XIAO and expands to 8 Grove connectors, including two Grove IIC and one UART. It acts as a bridge for Seeeduino XIAO and Seeed's Grove system, which provides 300+ of different Grove modules including sensor, actuator, communication, display, etc. No more jumper wires and soldering work, you could enjoy creating more projects with Seeeduino XIAO easily and quickly.


With the on-board battery management chip and battery bonding pad, you could easily power your Seeeduino XIAO with lithium 3.7V battery and recharge it, making your projects, especially wearables ones, more flexible and in portable. You could even break the board through the onboard PCB stamp holds according to your actual needs of the project (only 25*39mm in dimension after break-off), making it smaller than smaller.

As an extension board, the Grove Shield for Seeeduino XIAO also pulls all 14 pinout from Seeeduino XIAO, and its on-board power switch and charging status indicator light makes it more user-friendly. The Shield even reserves the SPI-Flash bonding pad for an advanced developer who may need to add Flash to Seeeduino XIAO to expand its memory space, providing Seeeduino XIAO with more possibilities.

If you are a fan of Seeeduino XIAO already, you would not miss this Grove Shield; if you are hesitating to have one because of the scare of soldering works, it is the chance to start the wonderful experience with Seeeduino XIAO now!


A pair of non-soldered 7-pin headers are accompanied in the product of Seeeduino XIAO. You could solder them before connecting Seeeduino XIAO with this Shield by plugging the soldered pin headers into the female headers on the Shield.

What is Grove?

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfil a variety of needs. Not only are these open hardware, but we also have open-source software.


For all Grove users (especially beginners), we provide you with the guidance of operation. Please read the instructions through the official website before your using the product.

    Small and functional but not Linux friendly
    Fired up all three that came in the three-pack and they are fine. Spent considerable time trying to get them working on Linux (Mint) using the Arduino IDE with (nearly) no success. Tried to flash them about a dozen times and only got it to work once. I suspect there is something messed up with the USB drivers. The only reference on the Seeed website to using Linux and the Arduino IDE for the Xiao is a post on their blog that simply says “Run arduino-linux-setup.sh”. I did that and it did seem to improve the USB responses in syslog when I plugged the board in. Still only got it to work once.

    Set it up in Windows and it worked perfectly fine, every time. Next ill try Arduino CLI but given my experience with the GUI IDE, I don’t think the CLI version is going to work either.

    I haven’t logged a lot of hours working with these yet but they appear to be a good choice if you need something REALLY small and only need to make a few external connections. You should also know that the memory is limited on these. The vaunted “blinky” sketch that we’ve all run a million times occupies 13% of available memory. Again, this shouldn’t be a problem as you aren’t going to be controlling eight motors and connecting to 12 sensors with one of these.

    Perfect! Level up for Arduino users
    This beautiful tiny microcontroller is absolutely perfect for anyone trying to level up their arduino projects. The only pain is you need to buy a pack a cheap pack of level shifters (I recommend a 10pk of 4-channel two-way shifters) to convert any 5v signals to the 3v the XIAO needs.
    The XIAO is beautiful, tiny, fast, and has so so much more memory for long programs compared to the arduino uno or nano.
    The blazing fast clock speed makes controlling stepper motors that much better.
    USB-C is another bonus.
    Soldering on the pins is a breeze. (if you want to use them- another advantage is soldering straight to wires for small applications)
    Have fun!
  3. Product Quality
    This is a great little arduino compatible device.
    It took sometime to find the library, but as always google is your friend. After I added the support for the board it runs without any problem. I am using it now for variety of projects involving I2C and SPI devices. Make sure you have USB-C for this one. I am using an adapter from micro USB connector to USB-C.
  4. Product Quality
    It is amazing , break off and became a more tiny board, it is perfect for my DIY project.
  5. Product Quality
    It is nice use for Seeeduino Xiao to make my project.
