With 3 hardware serial ports on the Maple, it is unlikely that SoftwareSerial would be needed until one realizes that some Arduino libraries (Adafruit’s GPS, for example) inherit from SoftwareSerial. If you are just out for a day’s playing, modifying the GPS library may not be something you really wish to do.

SoftwareSerial Library
The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). The native serial support happens via a piece of hardware (built into the chip) called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.
The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name 'SoftwareSerial').
Nextion + Arduino Due: SoftwareSerial Issue
Limitations
Because it's not supported by hardware, the library has a few limitations:
- Only speeds up to 9600 baud work
- Serial.available() doesn't work
- Serial.read() will wait until data arrives
- Only data received while Serial.read() is being called will be received. Data received at other times will be lost, since the chip is not 'listening'.
SoftwareSerial appears to have some timing issues and/or software issues. Check this forum thread for discussion.Software Serial Discussion. In particular, if you are having problems using SoftwareSerial with an Atmega168 chip delete SoftwareSerial.o in your Arduino directory.
