Description The Seeed Studio LinkStar-H68K-1432 V2 is a compact indoor router and edge device built around the Rockchip RK3568 quad-core Cortex-A55 processor. It combines dual 2.5GbE ports, dual 1GbE ports, Wi-Fi 6, 4GB memory, 32GB eMMC storage, USB expansion, HDMI 2.0 4K output, and multi-OS support for OpenWRT, Armbian, and Android 11. Compared with the first H68K generation, the V2 improves communication, heat dissipation, power input, and port layout. It is well suited for a high-speed VPN router, personal NAS, remote access gateway, firewall, print server, media player, or compact Docker host. Features High-speed networking with two 2.5GbE ports and two 1GbE ports for flexible routing and gateway deployments. Dual-band Wi-Fi 6 based on the MT7921E module, supporting 2.4GHz and 5GHz wireless networking. Rockchip RK3568 quad-core 64-bit Cortex-A55 platform with ARM G52 2EE GPU and 1 TOPS INT8 NPU. 32GB onboard eMMC, microSD expansion, USB 3.0 Type-A, USB 2.0 Type-A, and USB 3.0 Type-C storage/SATA expansion. HDMI 2.0 output for up to 4K@60fps video playback, with Android 11 pre-installed and OpenWRT/Armbian support. USB-C power input with 5V-20V wide-voltage DC support, more than 10W power requirement, and CC-line PD fast charging. H68K V2 Improvements Area H68K V2 update USB One external USB 2.0 Type-A port, one external USB 3.0 Type-A port, and one internal USB 2.0 Type-A port in the PCIe M.2 slot for MT7921 Bluetooth function. SATA The Type-C port supports SATA function in the docking dock. Type-C Power Supports CC-line PD fast charging and 5V-20V wide-voltage DC input with a power requirement above 10W; the 12V DC interface power supply is removed. Interface Layout The network port layout is neater for easier cabling. Enclosure Integrated heat-dissipation strip and an industrial-style metal enclosure improve cooling. Production Support H68K V2 is the mass-production version listed by the manufacturer. Applications VPN router, firewall gateway, ad-blocking gateway, and remote access node. Personal NAS or lightweight server using eMMC, microSD, USB, and high-speed Ethernet. Travel router or Wi-Fi repeater for hotels, cafes, office networks, and portable work setups. 4K media player or dashboard display with HDMI 2.0 output and Android 11. Docker-based home services such as private cloud, media service, automation, or network tools.
