Beken — 2 prefixes (MA-L); Wi-Fi MCU / BT-audio SoCs, OUI ≠ device brand (Tuya smart-home)

About this vendor.

Updated  ·  Confidence: High

Beken holds 2 MA-L blocks (about 33.55 million addresses) registered as "Beken Corporation" at Building 41, Capital of Tech Leaders, 1387 Zhangdong Road, Zhangjiang High-Tech Park, Pudong New District, Shanghai, China. Verified samples are 70:87:9E and C8:47:8C. These OUIs appear on Wi-Fi MCU SoCs (the BK72xx series), Bluetooth-audio SoCs, and IoT connectivity modules. The BK72xx Wi-Fi MCU is especially significant for smart-home triage: Beken's BK7231T powers Tuya WB-series modules (e.g., WB3S) and the BK7231N powers Tuya CB-series modules (e.g., CB3S/CBU), which are the standard MCUs inside Tuya smart sockets, bulbs, and switches. The key analyst point is the chipset pattern: a Beken OUI identifies Beken silicon regardless of the brand on the box, and because the BK72xx is such a frequent substrate for Tuya white-label gear, a Beken OUI strongly suggests a low-cost IoT or smart-home endpoint. For triage, a Beken OUI in ARP/DHCP means a low-cost Wi-Fi IoT endpoint built on Beken silicon — classify it as smart-home/IoT (likely Tuya-ecosystem), not as a specific brand.

Wi-Fi MCU SoCs (BK72xx series), Bluetooth-audio SoCs, IoT connectivity modules [Confirmed] — maclookup.app
Notable products
BK7231T (powers Tuya WB-series, e.g., WB3S), BK7231N (powers Tuya CB-series, e.g., CB3S/CBU) — standard MCUs in Tuya smart sockets/bulbs/switches [Likely] — Tuya developer docs, OpenBeken project
Verified prefix sample
70:87:9E, C8:47:8C [Confirmed] — maclookup.app
Special note
Chipset-OUI flag. A Beken OUI identifies Beken silicon regardless of brand; the BK72xx is a frequent substrate for Tuya/smart-home white-label gear, so a Beken OUI strongly suggests a cheap IoT/smart-home endpoint. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

Analyst note
A Beken OUI in ARP/DHCP means a low-cost Wi-Fi IoT endpoint built on Beken silicon — classify as smart-home/IoT (likely Tuya-ecosystem), not as a specific brand.
