NANO UNO Multipurpose Expansion Board Multipurpose Expansion Module
The RO NANO multi-purpose expansion board is a sensor expansion board tailored for DUINO NANO. It solves the problem of wiring confusion when NANO connects multiple sensors and becomes a powerful tool for you to open DUINO works.
1. Lead out all digital IO ports and analog IO ports, each IO port has a standard positive and negative power interface
2. Lead out the I2C interface on the motherboard to facilitate the connection with I2C devices
3. Increase the DC power supply interface. The USB interface power supply current on the NANO board is actually only 50MA. It is obviously insufficient when devices with large currents such as steering gears are required. At this time, an external power supply is provided at the DC power supply interface.
