ODROID-U2 is the predecessor of ODROID-U3 and shares most of its hardware design (2 GB LPDDR2 RAM, LAN9730 10/100 Ethernet on HSIC0, USB3503A hub on HSIC1, MAX98090 audio codec with headphone jack and on-board MEMS DMIC, MAX77686 PMIC, PWM-controlled cooling fan header, blue heartbeat LED). Key differences from ODROID-U3: - The micro-USB (DWC2 / hsotg) port does not have a VBUS supply switch, so it operates only in peripheral mode (dr_mode = "peripheral"). - The 3.5 mm jack is headphone only, and the board features an on-board MEMS digital microphone (DMIC) rather than an analog mic input. - There is no expansion header with SPI. Hardware verification was performed on a physical ODROID-U2 board running Linux 6.12: - DWC2 USB: verified in peripheral mode via /sys/class/udc and dmesg. - Ethernet: SMSC LAN9730 detected on HSIC0, link up at 100 Mbps Full-Duplex. - Storage: microSD (mmcblk2) detected and functional. eMMC was not tested, as no eMMC module was available. - Thermal: /sys/class/thermal/cooling_device0/type shows pwm-fan (no fan was attached). - Audio: * Stereo headphone playback verified with speaker-test and aplay. * On-board digital MEMS microphone (DMIC) recording verified with: amixer -c OdroidU2 cset name='DMIC Mux' DMIC arecord -D hw:OdroidU2,0 -f S16_LE -r 48000 -c 2 -d 5 /tmp/dmic.wav aplay -D hw:OdroidU2,0 /tmp/dmic.wav Audio routing includes "Mixer DAI RX", "HiFi Capture" connecting the MAX98090 codec capture to the Exynos I2S controller. - LED: blue:heartbeat blinking with heartbeat trigger.
