Odroid-C4 might be the odroid you ‘re looking for.


    Hardkernel has launched a $50 “Odroid-C4” SBC that runs Linux or Android on a 2GHz, quad Cortex-A55 Amlogic S905X3 with 4GB DDR4, an eMMC slot, 4x USB 3.0, GbE and HDMI, and a 40-pin GPIO.

    Hardkernel’s new open-spec Raspberry Pi Four competitor and lookalike is the primary community-backed SBC we’ve seen to combine Amlogic’s new S905X3 SoC. The $50 Odroid-C4 is inheritor to the equally open-spec Odroid-C2, which was one of the common rivals of the Raspberry Pi 3. The Odroid-C4 will doubtless be one of many largest hacker board introductions of the 12 months, particularly contemplating the pipeline of recent SBC fashions has slowed in early 2020.

    The Odroid-C4 falls between Hardkernel’s growing older, low-end Odroid-C0 and Odroid-C1+ boards, that are based mostly on a quad -A5 Amlogic S805, and final 12 months’s $63 to $79 Odroid-N2 on the excessive finish with its hexa-core Amlogic S922X (4x 1.8GHz -A73, 2x 1.9GHz -A53). It’s arguably a step up from the growing older, SATA-ready Odroid-XU4, which nonetheless beats the Odroid-C4 on many of the Hardkernel CPU and GPU benchmarks mentioned under. (See our up to date catalog of 136 Linux hacker boards for a comparability chart amongst these and different community-backed SBCs.)

    The 12nm fabricated Amlogic S905X3 is a modest replace of the S905X2, shifting from 4x Cortex-A53 cores to 4x Cortex-A55 cores with the identical 2GHz most clock. Just like the S905X2, the S905X3 has a Mali-G31 GPU and is equally targeted on the Android TV field market. In contrast to the S905X2, the S905X3 is offered with an elective 1.2-TOPS neural chip and Cortex-M3 and -M4 MPUs, however these choices aren’t obtainable on the Odroid-C4.

    Though the Raspberry Pi Four has extra highly effective Cortex-A72 cores, the SBC is clocked to 1.5GHz in comparison with 2GHz on the Odroid-C4. Hardkernel has posted benchmarks displaying superior CPU and GPU efficiency in contrast with RPi Four and a lot better than the Odroid-C2. It seems to be significantly sturdy in multi-core CPU efficiency, reminiscence bandwidth, and low energy consumption. Arm claims that the Cortex-A55 structure delivers as much as 18 % larger efficiency and 15 % higher energy effectivity in comparison with the Cortex-A53.

    The CNXSoft story that alerted us to the C4 means that efficiency is probably going much like that of the Khadas Vim3L. This scaled-backed spin-off of the Vim3 has a quad -A55 Amlogic S905D3 SoC with a Mali-G31, in addition to a 1.2-TOPS GPU, however solely has 2GB as a substitute of 4GB of RAM on the C4. It lately jumped in worth from $50 to $70.

    If the Odroid-C4 is certainly quicker than the Raspberry Pi 4, that’s not its solely benefit. In contrast to the RPi 4, there’s open eMMC socket and 4x USB 3.Zero host ports as a substitute of a mixture of USB 3.Zero and a pair of.0. You additionally get wide-range energy and an IR receiver. The RPi 4, nevertheless, has a second HDMI port, MIPI-DSI and -CSI, and built-in WiFi/Bluetooth, and it sells for $5 much less.

    The Odroid-C4 is additional outfitted with 4GB LPDDR4, a microSD slot, GbE and USB OTG ports, serial debug, an audio header with SPDIF, and a 40-pin GPIO header. There are quite a few choices, together with a case. Supported distributions embrace CoreELEC, Android 9, LineageOS, and Ubuntu 20.04 LTS, which launched immediately.

    Specs listed for the Odroid-C4 embrace:

    • Processor — Amlogic S905X3 (4x Cortex-A55 @ as much as 2GHz); 12nm fab; Mali-G31 GPU @ as much as 650MHz
    • Reminiscence/storage:
      • 4GB LPDDR4 RAM (2640 MT/s)
      • empty eMMC socket with elective 8GB to 64GB
      • MicroSD slot
    • Networking:
      • Gigabit Ethernet port (Realtek RTL8211F) with 2x LEDs
      • Optionally available WiFi USB dongle
    • Media I/O:
      • HDMI 2.Zero port for as much as [email protected] with audio output
      • Audio header with I2S, DC 5V, and SPDIF-out with elective SPDIF optical output
    • Different I/O:
      • 4x USB 3.Zero host ports
      • Micro-USB 2.Zero OTG port (no energy)
      • Serial debug console
      • 40-pin GPIO header (2x I2C, SPI, UART, 6x PWM, 2x ADC, as much as 25x GPIO, 2x DC 5V, 2x DC 3.3V, DC 1,8V, 8x GND)
    • Different options — IR receiver; heatsink; case ($4.50); quite a few choices together with eMMC, microSD playing cards, cables, shows, and USB, audio, and GPIO based mostly add-ons
    • Energy – 5.5-17V DC enter with LEDs and elective adapters (12V advisable); consumption: 3.64W CPU stress, 1.8W idle, 0.14W off
    • Dimensions — 85 x 56 x 1.0mm
    • Weight — 59 g together with heatsink
    • Working system — Ubuntu 20.04, CoreELEC, Android 9, LineageOS
