ODROID-HC4 with OLED

Author: Momnaa Ikram

The ODROID-HC4 is a brand-new home cloud platform that uses the same ARM CPU as its predecessor, the ODROID-C4. The CPUs used are Cortex A55 quad-core processors with 4 GB of DDR4 RAM. Petit-boot is based on a 16 MB SPI flash chip that is put on the board and is used to boot the system.

In addition, a PCIe to SATA direct bridge solution is used to connect the two drives. It is possible to connect up to two 2.5” or 3.5” hard drives to the HC4 board and transport data at speeds of up to 500 MB/s under ideal conditions, thanks to the inclusion of two SATA memory docks.

On the back of the transparent casing, you’ll find a 5.5 mm DC socket, a micro SD slot that’s compatible with UHS-1, a USB 2.0 connector, an HDMI port, and a 1 Gigabit LAN port. If you have a large mechanical drive and an SSD for caching hard discs for use in RAID configurations such as RAID 0, you may build RAID 0, 1, or optimize I/O with a large mechanical drive and an SSD for storing hard discs to be used in RAID configurations such as RAID 0. (LVM, bcache, etc.).

Features:

• DDR4-SDRAM memory with a capacity of 4 GB (PC4-21333)
• There are two SATA interfaces.
• LAN port capable of ten gigabits per second
• HDMI 2.0 supports resolutions of up to 4K at 60 Hz.
• To put it another way, the host port for USB 2.0 is referred to as the status LEDs (two)
• The UART controls the graphical user interface of the system.
• This receiver receives infrared waves.
• At least five general-purpose input/output (GPIO) pins (for the OLED display)
• Memory card reader with a Micro SD card slot (which accepts cards up to UHS-I SDR104 speed).
• Connector for the fan
• The power switch
• Connection of a direct current power source (5.5 mm on the outside, 2.1 mm on the interior)
• Four amps of current: 14.5 to 15.5 Volts DC
• The cooler has the following dimensions: 40 x 32 x 10 mm.
• The board measures 84 x 90.5 x 25 mm in dimensions (LxWxH).

Who should be interested in this board?

Petitboot can be used to boot the HC4 from a hard drive or solid-state drive (SSD) connected to your computer, even if you do not have an SD card accessible. If you’re looking for a feature like this, the board is an excellent choice. Using the OLED display will make it easier for time tracking.

What should users know about it?

Pros

• The HC4 is equipped with IO ports on the back.
• The Quality of Service (QoS) of the SATA Interface is effortless and efficient
• 4 GB of DDR4 RAM is significantly faster.
• Processors with four cores that consume less energy were designed and developed.
• clock-watching
• Electricity savings
• This is a well-thought-out layout.
• Thermals that are suitable for use with Petiboots

Cons

• A scarcity of general-purpose input/output (GPIO) ports
• It’s a significant sum of money.

THE BOTTOMLINE

This device, which includes both the real-time clock integrated circuit and a 1-inch OLED panel for displaying system status information, costs $75 to purchase and ship. Because the Plus version is only $10 more expensive than the standard version, it is almost sure to be a smash. The only additional expenditure is the purchase of storage drives.
