This is a convenient input/output port board that can be used by plugging directly into the 14-pin header connector of ODROID-M1S.
USB 2.0 host, Power button, Reset button, Audio line-out 3.5mm phone jack and I2C & UART buses are available on a small board.
System power noise may affect the audio circuitry, resulting in background noise in the audio output. Therefore, we recommend that our customers do not use the phone jack output in applications requiring high sound quality.
