ODROID-HC4 (OLED ile)

Ürün Açıklaması

AÇIKLAMALARODROID-HC4 is new Home-Cloud platform based on the same ARM CPU as the ODROID-C4. We adopted a 12nm fabricated energy efficient 1.8Ghz Cortex-A55 quad core processor with faster 4GB DDR4 RAM. A 16MiB SPI flash chip exists on the board for the useful Petitboot feature.Technical information at WiKi : https://wiki.odroid.com/odroid-hc4/odroid-hc4We adopted a 12nm fabricated energy efficient 1.8Ghz Cortex-A55 quad core processor with faster 4GB DDR4 RAM. A 16MiB SPI flash chip exists on the board for the useful Petitboot feature.We decided to drop the use of USB3.0 to SATA bridge solutions (quirks, additional IO layer, etc) for the ODROID HC4. We are therefore using a more native and reliable PCIe to SATA direct bridge solutions. In doing so the HC4 board provides two SATA storage docks.A 5.5mm DC power jack, UHS-1 compatible micro-SD slot, USB 2.0, HDMI 2.0 and 1GbE port are available on the rear side of the transparent shell case.Circuit BoardACPU (Amlogic S905X3)H2x System LED indicatorsBDDR4 memory (4GiB)I1x UART for system consoleC2x SATA portsJ1x IR receiverD1x RJ45 Ethernet port (10/100/1000)K5x GPIO pins (for optional OLED display)E1x HDMI 2.0L1x Micro SD slotF1x USB 2.0 host portM1x Cooling fanG1x DC power jack (Outer diameter : 5.5mm, inner diameter 2.1mm)N1x Boot switchThe toaster form factor ODROID HC4 accepts 2 x 3.5? or 2 x 2.5?? mechanical or SSD disks. You can obviously also use one mechanical and one SSD. See two examples shown below. Thanks to Linux LVM or mdadm you can combine two disks in RAID 0, RAID 1 or optimize IO with a large disk using one mechanical drive and an SSD for disk caching (LVM, bcache, etc).Two 12TB high performance HDDs on the HC4Two Samsung SSDs on the HC4Block diagramSATA interface performanceWe connected a SATA SSD to the HC4 platform and measured the storage IO throughput. We could observe 390~420MB/s transfer speed which is not saturated at the maximum level ~500MB/s which is quite good for many applications.odroid@...
