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

As Jallson Suryo discusses in his project, adding voice controls to our appliances typically involves an internet connection and a smart assistant device such as Amazon Alexa or Google Assistant. This means extra latency, security concerns, and increased expenses due to the additional hardware and bandwidth requirements. This is why he created a prototype based on an Arduino Nicla Voice that can provide power for up to four outlets using just a voice command. Suryo gathered a dataset by repeating the words “one," “two," “three," “four," “on," and “off” into his phone and then uploaded the recordings to an Edge Impulse project. From here, he split the files into individual words before rebalancing his dataset to ensure each label was equally represented. The classifier model was trained for keyword spotting and used Syntiant NDP120-optimal settings for voice to yield an accuracy of around 80%. Apart from the Nicla Voice, Suryo incorporated a Pro Micro board to handle switching the bank of relays on or off. When the Nicla Voice detects the relay number, such as “one” or “three," it then waits until the follow-up “on” or “off” keyword is detected. With both the number and state now known, it sends an I2C transmission to the accompanying Pro Micro which decodes the command and switches the correct relay.
