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 helps you get rid of breadboard and jumper wires. With the 16 onboard Grove Connectors, you can easily connect with over 300 Grove modules! The pinout of Base Shield V2 is the same as Arduino Uno R3.

Highlighted Features

There are 16 onboard Grove connectors including 4 x Analog, 7 x Digital, 1 x UART, and 4 x I2C. Apart from the rich Grove connectors, on the board you can also see an RST button, a green LED to indicate power status, an ICSP pin, a toggle switch, and four rows of pinouts. There is no need to explain the RST button and LED, but you really need to know two features below 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 microcontroller 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 microcontroller 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 a 5V position; while using Seeeduino Arch with Base Shield V2, please turn the switch to 3.3V.

2. Board Compatible:

The pinout of Base Shield V2 is the same as Arduino Uno R3, however, Arduino Uno is not the board that the Base Shield V2 is compatible with, here we listed the boards that we have confirmed can be used with Base Shield V2.
