Hardkernel recently introduced the ODROID-H3 and H3+ SBCs as successors of the ODROID-H2+ board released a couple years ago. These boards support up to 64GB RAM, dual 4K displays, dual 2.5 GbE ports and flexible storage interfaces.

The 10 nm Intel processors found on the H3 and the H3+ have the following features:

• Celeron N5105— 4C/4T, 2.0GHz – 2.9GHz (10W), 4M L3 Cache; UHD Graphics (up to 900 MHz)
• Pentium Silver N6005 — 4C/4T, 2.0GHz – 3.3GHz (10W), 4M L3 Cache; UHD Graphics (up to 800 MHz)

According to Hardkernel’s wiki, both boards support up to 64GB dual-channel DDR4 (up to 32GB per slot), one M.2 socket for NVMe storage, two SATA 3.0 ports (6.0GB/s), and one eMMC socket.

The display interface provides one DisplayPort 1.2 and one HDMI 2.0 for simultaneous displays. Both ports support [email protected] resolution. There is a 3.5mm audio jack, but the DP and the HDMI port seem to have audio output as well according to the ODROIDforum. 

The networking interface features dual 2.5 GbE LAN ports stacked over two USB 3.0 and two USB 2.0 ports as shown in the image below.

Both boards feature a DC power jack supporting up to 60W (14V-20V). It’s recommended to use a 19V/7A DC power adapter if two 3.5” HDDs are used. If not, a 15V/4A DC power adapter might be sufficient. 

The company also mentioned that the H2 series cases and the ODROIDH-series Net card are compatible with these new two boards. For reference, both boards seem to measure 110 x 110 xx 47mm.
