Challenges in RK3588 Advertising Board Sourcing
| Sourcing challenge | Industry problem | AndroidSBC solution |
|---|---|---|
| CMS and platform lock-in | Many budget advertising boards ship with a closed player that only works with the factory's own CMS, so a network migration or client CMS requirement strands every installed unit | ADB boards are tested against Xibo, ScreenCloud, and NoviSign plus Android Enterprise management, so integrators and brand owners can run the CMS their client already uses |
| Single-screen hardware in a multi-screen world | Most entry boards drive one HDMI output, forcing buyers to install one player per screen for menu boards, video walls, and dual-display layouts, multiplying cost and failure points | ADB-300 dual, ADB-400 quad, and ADB-500 six-output boards drive independent content or frame-synced walls from one chip |
| Memory and storage SKU mismatch | Buyers order boards without matching RAM and eMMC to the actual workload, causing stutter on 8K content, app reloads on interactive kiosks, and storage exhaustion on media libraries | Each ADB model offers three memory and storage SKUs from 4GB LPDDR4 plus 32GB eMMC to 16GB LPDDR5 plus 128GB eMMC, matched to the deployment before production |

Q: Which memory and storage configurations are available?
A: Each ADB model ships in three memory and storage SKUs. The featured ADB-300 is available as 8GB LPDDR4X + 64GB eMMC (for retail dual-screen advertising). Buyers match the RAM and eMMC to the workload before production so 8K playback, interactive apps, and media libraries run without stutter.
Q: Do the boards work with third-party CMS platforms?
A: Yes. ADB boards are tested against Xibo, ScreenCloud, and NoviSign, and support Android Enterprise management, so they can join the CMS your client already uses, or we preload your own CMS app under an OEM program.
Q: Can one board drive multiple screens with independent content?
