We already knew Hardkernel was working on ODROID-C1+ development board, an update the popular ODROID-C1 board with the same Amlogic S805 processor, storage and memory, but with a standard HDMI port replacing the micro HDMI port, I2S support, better micro SD card and HDMI-CEC support, an micro USB OTG port that can be used to power the board, and an included heatsink. The board is now up for sale for $37, or just $2 more than the original ODROID-C1 board.

ODROID-C1+ launch means ODROID-C1 is now officially phased out. Please note that changes made to the hardware means ODROID-C1 heatsink and plastic enclosure are incompatible with ODROID-C1+. The software however is compatible, and you can download Android and Ubuntu images & source code and access documentation on ODROID-C1(+) Wiki.
Since I2S pins are now exposed, the company also designed an HiFi shield for ODROID-C1+ with gold-plated stereo RCA connectors and a 3.5mm stereo jack, and based on Texas Instruments PCM5102 DAC chip supporting 16 to 24 bit audio formats, and up to 192kHz sampling rate.
The HiFi board can be used with various audio playback systems such as Volumio, RuneAudio or Kodi. C1+ HiFi shield sells for $39 + shipping. More details about the HiFi board can be found on its product page. ODROID-C1+ plastic enclosures don’t seem compatible with the HiFi board however.
