WebDec 21, 2024 · In the case of Arduino Uno, we have only one serial port which is available on Pin0 and Pin1. Pin0 = RX. Pin1 = TX. Using the Arduino’s default Serial Port we can connect only one serial communication supported device. But when it comes to the multiple Serial devices then the Arduino default serial port becomes insufficient. WebDec 28, 2024 · Maybe that's what you were referring to, but OP only needs TX. As far as I can see, you can use the same RX pin on all your SoftwareSerial instances. You'd only have to "sacrifice" one pin. You could also have single serial connecting that's shared with all the Nanos, and add an id to each message.
