Base Shield V2

Description:

Grove Connector Details:

There are in total 16 grove connectors on the Base Shield, here we use a table to show the details.

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 row of pinouts. There is no need to explain the RST button and LED, but you really need to know below two features that is very important for your usage.

• Power Compatible: Every Grove connector has four wires, one of which is Vcc. However, not every micro-controller main board needs a supply voltage of 5V, some need 3.3V. That’s why we add a power switch to Base Shield v2. In this way, you can adjust the voltage of Vcc via this switch, making sure the voltage of Vcc is the same as supply power of the main board.
• So While 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 number of pinout is the same as that of Arduino UNO R3.
• Added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes. —- According to Arduino UNO.

2.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.

• Arduino Uno
• Seeeduino V4.2
• Arduino Mega / Seeeduino Mega
• Seeduino LoraWan
• Arduino Leonardo / Seeeduino Lite
• Arduino 101
