Giada DN84-A-4G Rockchip RK3576 Android Digital Signage Player with HDMI Input and 4GB RAM

Some screens need to show live feeds, a broadcast channel or a presenter’s laptop as well as scheduled signage. The Giada DN84-A-4G is a fanless Android digital signage player on the Rockchip RK3576 that adds a 4K HDMI input to its two HDMI outputs, so a live source can be brought into the signage app. It is part of the DN84 series with the DN84-A-8G and the output-only DN84-4G.

The RK3576 combines four Cortex-A72 and four Cortex-A53 cores at a 6 W TDP with a Mali-G52 MC3 GPU and a 6 TOPS NPU that supports INT4 to FP16 and BF16 models. On the DN84-A-4G that runs Android 14 or Debian 12 with 4 GB of onboard LPDDR4 and 64 GB of eMMC, with 128 GB of eMMC optional and an M.2 2242 PCIe 2.1 x1 slot for an SSD when content libraries grow.

There is one Gigabit Ethernet port, with a second RJ45 optional, and dual-band Wi-Fi and Bluetooth onboard. An M.2 B-Key slot with a SIM socket takes an optional 4G module. Three USB 3.2 Gen1 ports and one USB 2.0 OTG port cover touch overlays and USB media, one RS232 port handles screen control, with a further RS232 and two RS485 optional, and a two-in-one headset jack carries audio.
