An RK3328 board is an embedded Android computer based on Rockchip’s quad-core Cortex-A53 processor. It is mainly used for 4K HDMI media playback, digital signage and cost-effective commercial display devices.
Yes. The RK3328 platform supports H.265, H.264 and VP9 hardware video decoding at up to 4K 60fps. Actual performance depends on the video profile, bitrate, player, firmware, storage and display.
The RK3328 processor supports HDR10 and HLG. The final HDR result depends on the source video, firmware, HDMI connection and display compatibility.
RK3328 supports H.264 and H.265 video encoding at up to 1080p. Its higher 4K capability applies to video decoding.
The AD-B01 provides HDMI 2.0 output for connecting a compatible monitor, television or commercial digital signage display.
The current AD-B01 specification focuses on HDMI output and does not list direct LVDS, eDP or MIPI display interfaces. Projects requiring a direct LCD connection should consider another SUNCHIP board.
Yes. The current AD-B01 configuration lists one RJ45 interface supporting 10/100/1000 Mbps Ethernet.
The current specification lists six USB host connections and one USB 3.0 connection. The connector layout and simultaneous peripheral requirements should be confirmed before production.
Android 7.1 is the current standard configuration listed for the AD-B01. Projects requiring newer Android APIs should consider a newer board such as RK3566.
Linux support depends on the available SUNCHIP BSP, drivers and project scope. Customers requiring Linux should confirm the required kernel, interfaces and long-term software support before ordering.
RK3328 can support basic kiosk applications using compatible USB touchscreens, scanners, printers and card readers. More demanding kiosk software may require RK3566 or another newer processor.
The board can be evaluated for selected 4G modules. Compatibility depends on the module interface, Android driver, frequency bands and target market.
Yes. SUNCHIP can evaluate boot branding, APK installation, kiosk mode, automatic startup, network settings, OTA updates, peripheral drivers and recovery functions through its OEM and ODM service.
Continuous operation depends on the enclosure, power supply, ambient temperature, cooling and software workload. A project-specific aging and thermal test should be completed before making a 24/7 operating claim.
Upgrade to RK3566 when the project requires Android 11, stronger CPU performance, more RAM, direct LCD display interfaces, lightweight AI or more complex applications.
