This is SeeedStudio Base Shield V2.

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.

Features:

There are 16 on-board Grove connectors including 4 x Analog, 7 x Digital, 1 x UART, 4 x I2C. Apart from the rich Grove connectors, on the board you can also see an RST button, a green LED to indicating power status, 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 below two features that are very important for your projects.
