MicroUSB OTG port
get drivers on your host PC, which means that the resources in the
ODROID-C2 can be shared with other PCs. You can also add a mi-
cro-USB to HOST connector if you need an additional USB host port.
This port can also be used for power input.
General Purpose Input and Output (GPIO) ports
ADC for electronics and robotics. The 40 GPIO pins on an ODROID-C2
are a great way to interface with physical devices like buttons and
LEDs using a lightweight Linux controller.
called WiringPi that handles interfacing with the pins. We have al-
ready ported the WiringPi v2 library to ODROID-C2, as described in
Chapter 4. Note that all of the GPIO ports are 3.3Volt, and the ADC
inputs are limited to 1.8Volt. In addition, 7 I2S pins are available.
Serial console port
monitor the boot process, or log in to the ODROID-C2 to perform sys-
tem maintenance. Note that this serial UART uses a 3.3V interface,
and it is recommended to use the compatible USB-UART module kit
available from Hardkernel. A Molex 5268-04a (2.5mm pitch) is mount-
ed on the PCB, and its mate is Molex 50-37-5043 Wire-to-Board Crimp
Housing.
RTC (Real Time Clock) backup battery connector
when offline, just connect the Hardkernel's RTC shield with a Lith-
ium coin backup battery (CR2032 or equivalent) to the appropriate
GPIO pins.
