Overview
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.
| CPU (Amlogic S905X3) | 2 x System LED indicators |
| DDR4 memory (4GiB) | 1 x UART for system console |
| 4 x USB 3.0 host ports | 1 x IR receiver |
| 1 x RJ45 Ethernet port (10/100/1000) | 40 x GPIO pins |
| 1 x HDMI 2.0 | 7 x GPIO pins |
| 1 x Micro USB 2.0 port (OTG) | 1 x eMMC module socket |
| 1 x DC power jack (Outer diameter : 5.5mm, inner diameter : 2.1mm) | 1 x Micro SD slot |
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.
Note:
- The power consumption in “IDLE” is measured when a device is not being operated for 5 minutes since the CPU governor is set to ‘performance’.
- The measured power consumption is not absolute and could vary in certain conditions.
