Overview
Grove Base Shield provides a simple way to connect with Arduino boards and help you get rid of breadboard and jumper wires. With the 16 on-board Grove Connectors, you can easily connect with over 300 Grove modules! The pinout of Base Shield V2 is compatible with the Arduino UNO, Arduino Leonardo and the Arduino Mega.
The Arduino Shield usually has the same pin position as the Arduino development board and can be stacked and plugged into the Arduino to implement specific functions.
Power Compatible:
Every Grove connector has four wires, one of which is the VCC. However, not every micro-controller main board needs a supply voltage of 5V, some boards only need 3.3V. That's why we add a power toggle switch to Base Shield V2 so that you can select the suitable voltage of the micro-controller main board you are using via this switch.
For example, if you are using Arduino UNO with Base Shield V2, please turn the switch to 5V position; while using Seeeduino Arch with Base Shield V2, please turn the switch to 3.3V.
Board Compatible:
The pinout of Base Shield V2 is the same as Arduino Uno R3, however Arduino Uno is not the only one that the Base Shield V2 is compatible with, here we listed the boards that we have confirmed that can be used with Base Shield V2:
- Arduino Uno
- Seeeduino V4.2
- Arduino Mega / Seeeduino Mega
- Seeduino LoraWan
- Arduino Leonardo / Seeeduino Lite
- Arduino 101
- Arduino Due
- Intel Edison
- Linkit One

For well over one hundred years, people have been constructing machines that dispense fortunes to those who ask at the insertion of a coin and the push of a button. In modern days, this has taken the form of mobile apps that can be far more expansive, albeit with a lack of physical interaction. Seeing an opportunity to use an embedded speech recognition model in this kind of application, the Electronic Cats team built the aptly named Fortune Cat just in time for some Halloween fun. This small device, based on the Arduino Nano 33 BLE Sense, takes advantage of the onboard microphone to listen for words being spoken at the small cube. Performing the language processing is Cyberon’s Arduino Speech Recognition Engine, which was configured to listen for the wake phrase “Fortune Cat” and then later respond to “tell me my future” as its command phrase. After generating the model online, it was incorporated into the code via the DSpotter software development kit that lets the program check if either the wake or action phrase has been said and then act accordingly. In this case, asking Fortune Cat for your future will present one of 20 random phrases that get displayed on the OLED mounted to the top of the 3D-printed enclosure.
