OUI A0:53:94 is a single MA-L block registered to "Shenzhen zediel co., Ltd." at a Xixiang, Shenzhen, Guangdong address (postal 518000), China. The registrant is a Shenzhen-based OEM/ODM that builds ARM-based Android embedded boards and system-on-modules rather than a consumer-retail brand, so devices carrying this prefix are typically integrated into a third-party integrator's end product — industrial Android mainboards (Rockchip RK3126/RK3326/RK3399/RK3566/RK3568/RK3588 and Spreadtrum/UNISOC platforms), smart-home control hubs, access-control terminals, POS mainboards, tablets, digital photo frames, and network media-player boards. The vendor's RK3399 board, for example, is documented with Gigabit Ethernet plus PoE, dual-band Wi-Fi, and Bluetooth, running an older Android release. No CVEs, advisories, or threat-actor attribution were found for this OUI or vendor; security posture is inherited from the embedded Android version and each integrator's patch discipline, which varies. This is a single-prefix vendor entry: the block appears only in the MA-L (oui.csv) registry, not in MA-M (mam.csv) or MA-S (oui36.csv). Note that the "03 November 2021" date some third-party lookup tools show is a database-crawl artifact — IEEE publishes no per-OUI registration date — so it is not recorded here as a registration fact.

- Security context
- no CVEs, advisories, or threat-intel mentions found for this OUI/vendor; device class (industrial Android SOM, access control, kiosks) runs older Android and is integrator-maintained, so posture is unknown and risk is inherited [Likely] — zediel.com/products/rk3399.html
- Allocated date
- Unknown — IEEE publishes no OUI/MAC registration dates; oui.csv has no date column [Unknown] — IEEE MA-L
- Analyst note
- A0:53:94 reliably identifies genuine zediel-built hardware, but because zediel ships boards as OEM components, the surfaced device is usually an integrator's end product, not a zediel-branded one — OUI alone does not name the end device.
