Grove Base Shield 2.0 for Arduino UNO




Arduino Uno is the most popular Arduino board so far, however, it is sometimes frustrating when your project requires a lot of sensors or Leds and your jumper wires are in a mess. 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 the same as Arduino Uno R3.


There are 16 on-board Grove connectors including 4 x Analog, 7 x Digital, 1 x UART, 4 x I2C. Apart from the rich Groveconnectors, on the board you can also see an RST button, a green LED to indicating power status, ICSP pin, a toggle switch and four row of pinouts. There is no need to explain the RST button and LED, but you really need to know below two features that are very important for your projects.

  1. 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.


  1. Board Compatible:

The pinout of Base Shield V2 is the same as Arduino Uno R3, however Arduino Uno is not the board 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.


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 fulfill 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 guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your using of the product.

If using Base Shield v2 with Seeeduino V3, please solder the pads, P1 and P2.

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. We listed the more than 20 the most useful Arduino shields to help you extend more possibilities for your Arduino projects. Check our blog to learn more about Arduino Shields!
