Hi,
Is it possible tou use Read board as USB to TTL Converter? I have found this tutorial https://create.arduino.cc/projecthub/Pa … ter-475533 and I was wondering :? if for SparkFun board it would work as well.
Thanks in advance for the answer.
Cheers,

The RedBoard can work as a serial bridge by making the UART pins inputs so they do not contend with the lines on the serial UART as explained in the tutorial you linked. I discovered this from another engineer https://learn.sparkfun.com/tutorials/pc … -debugging. While slower, you can also use the ATmega328P as a software serial passthrough. Both examples are illustrated here with a GPS receiver => https://learn.sparkfun.com/tutorials/ls … e#examples.
As a quick note, I adjusted the software serial library for the LS20031 GPS receiver based on a customer’s comment. Most of the time you will not need to adjust the buffer in the SoftwareSerial.h.
