Note that the most natural way to make the Arduino Uno communicate with the NanoPi Neo is to use the USB interface. By plugging the Arduino on the NanoPi's USB port, you do not need any additionnal circuit. Since the USB port controls the reset pin of the ATmega328P, you could even upload programs t...

Hi, A common error is to try to connect with SSH to the wrong device. On the other hand, the starting of the system is very slow, and one have to be patient and wait enough before concluding it is not working. Your USB power supply must also provide enough current: the use of a 5V/2A USB charger is ...

Hi, Yes, it is possible to make an Arduino Uno and a NanoPi NEO talk to each other thru their RX and TX pins. However you have to face few problems. First of all, the NanoPi NEO provides and reads 3.3V digital signals while the Arduino Uno provides and reads 5V digital signals. A 5V RX input could r...
