Grove - Protoshield


This Grove allows you to add your own circuitry or components to your Grove system prototypes. It gives you access to all four lines from the grove connector cable – S0, S1, VCC and GND. There is also a reserved space for a normally-open button. Standard 2.54mm spacing makes it easy to install normal DIP-format ICs and other components onto the board.


  • Standardised Grove Interface
  • Breadboard style
  • Standard spacings
  • Silk screen labels
  • Reserved space for normally-open button


VCC and GND of the Grove interface are routed out as two buses as shown above. You can find soldering pads of Sig0 and Sig1 between two power buses.


VCC and GND of the Grove interface are routed out as two buses as shown above. You can find soldering pads of Sig0 and Sig1 between two power buses. They are marked out by white lines. The square area on the right is for a ubiquitous temporary button, you can easily snap one into it as shown below.

Also the protoshield is shipped with two 20-pin male headers. You can break them into smaller pieces and solder them onto protoshield when you need extension on other breadboard or protoboard. They work well with normal breadboard jumpers.

Demo: Light LED

  1. Insert the longer pin of LED into the VCC interface and the shorter pin into Sig0 interface.

  2. Solder LED on the Protoshield.

  1. Connect the module to the Digital 8 of Grove - Basic Shield using the 4-pin grove cable.

  2. Plug the Grove - Basic Shield into Arduino and connect Arduino to PC by using a USB cable.

  3. Copy and paste code below to a new Arduino sketch. Please click here if you do not know how to upload.

Demo code:
int led = 8;

// the setup routine runs once when you press reset:
void setup() {
    // initialize the digital pin as an output.
    pinMode(led, OUTPUT);

// the loop routine runs over and over again forever:
void loop() {
    digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(1000);               // wait for a second
    digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
    delay(1000);               // wait for a second


Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
