Gravity: Nano I/O Shield for Arduino Nano

SKU: DFR0012

The DFRduino Nano I/O Expansion Board enhances Arduino Nano and DFRduino Nano microcontrollers by providing multiple power inputs, compatibility with Arduino UNO form factors, sensor/servo connection ease, Bluetooth and ACP220 module space, and I2C pin access.

    1. APC/Bluetooth module serial jumper caps: When you make a program with Nano which is using Atmega328 chip, please remove the wireless device, or remove "TX" and "RX" jumper caps
    2. Nano Switch: The Nano shield is compatible with our Nano V3 and Nano V4. Since the difference the I2C interface, we add a switch on the shield, you could select the right board with the right I2C pins

    There are three jumper caps on the shield (APC/Bluetooth module serial jumper caps).
    When you want to power the shield with usb cable, please move 'GND' jumper cap to Servo power selection port.
    When you want to use external servo power, please move the jumper cap back.
    Or it will damage your microcontroller
