NANO and UNO multi-purpose expansion board ATMEGA328 Learning board for arduino nano 3.0 WAVGAT

 

 

Multi NANO NANO expansion board is tailored to a sensor expansion board to solve the problem of chaotic NANO wiring connecting a variety of sensors, it becomes your weapon development work. 

1 leads to all digital and analog IO port IO port, each IO port has positive and negative power supply interface standard 

2 on the motherboard connection leads I2C interface, convenient and I2C devices 

3 Increase DC power connector. USB interface, power supply current NANO board actually only 50MA, to bring high-current devices such as steering when it is clearly insufficient at this time to provide an external power supply DC power connector, ensure stable device operation.
