You still can get a third UART-1 by configuring some pins in MODE-2. Please check Expansion
for Processor Board section for a complete pin description and their possible modes.
UART PORTS ARE 1.8V LOGIC LEVELS. ENSURE YOU CONNECT DEVICES
COMPATIBLE WITH THESE LEVELS.

PROTON will give you an easy, quick and fast way to access to a complete I2C interface
through easily accessible 2.54mm pitch J21 connection. There is the possibility to configure
one I2C interface (MODE 0); the next table shows you the pins you can use for this feature:

PROTON will give you an easy, quick and fast way to access up to 4 PWM interface through
easily accessible 2.54mm pitch J21 connection by configuring the appropriate pins in MODE-2.
You will have to choose to use these pins as PWM ports (MODE-2) or UART-2 ports (MODE-0).
