ODROID C1 USER MANUAL
ODROID-C1+
T
he ODROID-C1+, released in August 2015, offers several new
features and improvements over the original ODROID-C1:
• HDMI connector was changed to Type A from Type D
The Type A connection allows a standard HDMI cable to be used with any com-
pliant HDMI monitor without the need for a Type D adapter or cable.
• Expanded microSD card compatibility
The original C1 model worked optimally with a specific set of microSD cards,
and using a non-compliant card would sometimes results in a slow-booting or
non-booting image. The C1+ is compatible with a wider array of microSD cards.
• Improved CEC functionality
The CEC harware has been updated to operate regardless of the presence of
an RTC backup battery.
• USB OTG power path
A small hardware modification could be performed on the original C1 model to
allow it to be powered via the USB OTG port. This modification is now standard
with the C1+ model by enabling the J8 jumper.
• I2S signals exposed for external audio DAC
The I2S signals can be easily accessed on the C1+ model in order to permit the
use of an external audio Digital-To-Analog Converter (DAC).
