HARDKERNEL ODROID-C4 4GByte
Egylapkás, a Raspberry Pi-hez hasonló kialakítású, de annál nagyobb számítási teljesítményű alaplap, nagy passzív hűtőbordával. Fejlett, cserélhető eMMC háttértáróló rendszer az operációs rendszer futtatására. (Pl. Linux, Android, Home-Assistant). Saját tervezésű eMMC-USB átalakító segítségével egyszerűen üzembe helyezhetőek az eszközök.
ODROID-C4 is a new generation single board computer that is more energy efficient and faster performing than ODROID-C2 which was introduced over four years ago as the world’s first affordable ARM 64bit computer.
The main CPU of the ODROID-C4 is built with a quad-core Cortex-A55 cluster with a new generation Mali-G31 GPU. The A55 cores run at 2.0Ghz without thermal throttling using the stock heat sink allowing a robust and quiet computer. The CPU multi-core performance is around 40% faster, and the system DRAM performance is 50% faster than the ODROID-C2.

GPIO (40Pin Header)
The ODROID-C4 GPIO interface is similar to C2 and fully supports a 3.3Volt interface. This is beneficial for using various peripherals without complicated level shifters as with the XU4’s 1.8Volt GPIOs. Another big improvement is a faster SPI bus interface with a maximum frequency of about 100Mhz. It is significantly faster than the ODROID-C2’s 400Khz software “bit-banged” SPI.
Power consumption
Thanks to the modern 12nm fabricated S905X3 CPU, the power consumption and heat dissipation are relatively very low.
Therefore, we can enjoy a quiet and powerful computer with high energy efficiency.
