| Memory | DDR4 4GiB with 32-bit bus width Data rate: 2640 MT/s (PC4-21333 grade) 1.2Volt low power design |
| Storage | 1x Micro SD slot (DS/HS mode up to UHS-I SDR104) |
| Networking | 1 x GbE LAN ports (RJ45, supports 10/100/1000 Mbps) - Realtek RTL8211F (Ethernet transceiver) - LED indicators * Green LED: Flashing by data traffics at 100Mbps connection * Amber LED: Flashing by data traffics at 1000Mbps connection |
| Video | 1 x HDMI 2.0 (up to 4K@60Hz with HDR, CEC, EDID) Although the +5V Power pin is able to supply a mininum of 300mA, a sink shall not draw more than 50mA of current from the +5V Power pin. |
| Audio | 1 x HDMI digital output |
| Cooler | 1 x Passive heatsink ( 40x32x10 mm ) on the CPU of PCB board 1 x Hydraulic Bearing FAN - Rated Voltage : 5V - Rated Current : 100mA - Max Speed RPM : 4,000 - Air Flow CFM : 4.3 - Air Pressure (In H2O) : 0.053 - Noise Level(dBA) : 23.9 - Dimension : 40 x 40 x 10.6 mm - Wire & Connector : 80mm, 4 pin 1.25mm pitch |
| External I/O | 1 x USB 2.0 host port 1 x Debug serial console (UART) 2 x SATA Connectors |
| Other features | IR receiver for remote controller System LED Indicators: - Red (POWER) – Solid light when DC power is connected - Blue (ALIVE) – Flashing like heartbeat while Kernel is running. Solid On in the u-boot stage. Turns off if there is no bootable media. - Red (HDD/SSD active) - Flashing while SATA HDD/SSD are reading or writing. |
| Power | 1 x DC jack : outer (negative) diameter 5.5mm, inner (positive) diameter 2.1mm DC input : 14.5V ~ 15.5V - DC 15V/4A power adapter is recommended Power consumption with two ST2000DM006 HDDs : - IDLE(with HDD in spin-down) : ≃ 5.88W - Active(using SAMBA): ≃ 15.59W - Suspend: ≃ 0.29W |
We recommend powering the ODROID-HC4 with a good quality 15V/4A power adapter.
