Hi All,
Designed a few arduino based low power data loggers over the last 3 years.
Thinking about purchasing a Mega Pro 3v3 for another low power data logger project.
Curious if anybody has tested using all 4 serial ports at the same time?
what is the highest baud rate that could be used?
Basically wondering if the move from 16MHz → 8MHz has any effect on operating 4 serial ports.
I understand that we are polling each sequentially with serial.available()
Also curious if anybody has any power consumption figures for when it is put in SLEEP_MODE_PWR_DOWN?
watch dog and brownout are disable in my current systems.
