ODROID-C4: An inexpensive and powerful Raspberry Pi alternative that even supports PSP emulation
Hardkernel, a well-known manufacturer of Raspberry Pi alternatives, has introduced ODROID-C4, its latest single-board computer. Measuring in at 85 x 56 x 1 mm, the ODROID-C4 incorporates an Amlogic S905X3 that features four ARM Cortex-A55 cores. These can clock up to 2.016 GHz and are cooled by a 59 g heatsink that measures 40 x 32 x 10 mm. The 12 nm processor also includes an ARM Mali-G31 MP2 GPU with four execution engines, which Hardkernel complements with 4 GB of DDR4 RAM that operates on a 32-bit bus at 2,640 MT/s.
Handling storage is an eMMC connector, with Hardkernel offering the board with up to 64 GB of storage. There is also a microSD card slot that supports up to UHS-I SDR104. Additionally, Hardkernel has included a Gigabit RJ45 port, while Wi-Fi can be added with optional USB adapters.
Meanwhile, an HDMI 2.0 port handles image output. Hardkernel claims that the ODROID-C4 can output in up to 4K at 60 Hz with HDR, CEC and EDID. Additionally, there is an optional SPDIF optical audio output. Accessories and peripherals can be connected via one of the board's four USB 3.0 Type-A or its USB 2.0 OTG port. A debug interface is available too, as is a 40-pin header. The header, which has 2.54 mm pitches, supports ADC, GPIO, I2C, PWM, SPI and UART.
The ODROID-C4 supports multiple OSes including Android 9.0 Pie, CoreElec and Ubuntu 20.04. Harkernel has demonstrated the ODROID-C4 emulating the PSP version of God of War too, as the video below shows. The ODROID-C4 is available to order from Hardkernel for US$50.
