Shenzhen Belon Technology Co., Ltd — 5 MA-L prefixes

A MAC address starting with 14:A4:17, 84:3E:79, A0:3C:31, B4:EE:25, or DC:4B:FE belongs to Shenzhen Belon Technology Co., Ltd, a Shenzhen-based IoT hardware maker. The company holds five separate IEEE MA-L block assignments rather than a single registration, which is itself a signal of an active, multi-product manufacturer rather than a shell filing.

The clearest product link is the BL2028N (and BL2028N-H001) Wi-Fi/BLE system-on-chip module, which turns up inside inexpensive smart switches and RGB/CW/WW smart bulbs sold through the Tuya cloud ecosystem. These devices are a known target of open-source firmware-replacement projects such as OpenBeken, and hobbyist teardown threads reference the module by name. An App Store developer account under the same company name publishes companion BLE lighting-control apps (MtBleLight, 智光秀, inLuxs), consistent with a smart-lighting hardware vendor.

One caution applies: two other, differently-branded companies share close variants of the "Belon" name — an ESD-safe packaging supplier (belonesd.com) and "Shenzhen Belon Solutions Co., Ltd," an intelligent-transportation-chip maker (en.belon.cn). Neither could be confirmed as the same legal entity as the OUI registrant, so neither is cited as this vendor's official site.

IEEE assignment

5 MA-L prefixes → Shenzhen Belon Technology CO.,LTD, registered Shenzhen, Guangdong, CN [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); 5 confirmed prefixes in the current registry [Confirmed] — the IEEE MA-L registry; cross-confirmed maclookup.app/vendors/shenzhen-belon-technology-co-ltd

HQ / country

Tsinghua Information, Shenzhen, Guangdong, CN 518052 [Confirmed] — the IEEE MA-L registry

Company status

no direct corroboration of a single unified corporate site; App Store developer account with apps published under the same name suggests ongoing activity [Likely] — apps.apple.com/us/developer/shenzhen-belon-technology-co-ltd/id1425809240

Device types

Wi-Fi/BLE IoT SoC module (BL2028N) powering smart switches and RGB/CW/WW smart bulbs in the Tuya ecosystem [Likely] — github.com/openshwprojects/OpenBK7231T_App, elektroda.com/rtvforum/topic3930515.html, elektroda.com/rtvforum/topic3932699.html

Notable products

BL2028N / BL2028N-H001 Wi-Fi/BLE module [Likely] — openbekeniot.github.io/webapp/devices/Aubess_DIY_Smart_Switch_(BL2028N_version).html

Verified sample prefixes (all MA-L, Shenzhen Belon Technology CO.,LTD)

14:A4:17, 84:3E:79, A0:3C:31, B4:EE:25, DC:4B:FE [Confirmed] — the IEEE MA-L registry, maclookup.app

Registration date

Unknown — IEEE's public OUI registry publishes no assignment/registration date field; maclookup.app displays "first registration 21 May 2019" / "most recent update 12 Jan 2023" but these are third-party database scrape artifacts, not IEEE facts

[Confirmed caveat] — maclookup.app/vendors/shenzhen-belon-technology-co-ltd

Name collision caveat

search results also surface an unrelated same-named ESD-packaging company (belonesd.com) and a separately-branded "Shenzhen Belon Solutions Co., Ltd" intelligent-transportation-chip maker (en.belon.cn); neither is confirmed as the OUI registrant [Confirmed ambiguity exists; Unknown which entity, if any, unifies them] — belonesd.com, belonesd.com/about, en.belon.cn

Security context

no vendor-specific CVEs or advisories found for Belon/BL2028N in this research pass; carries the generic risk profile of low-cost Chinese Wi-Fi/BLE smart-switch SoCs [Unknown] — no source found

Related vendors

none confirmed

Analyst note

five independent MA-L blocks plus an identifiable module product line and app-store presence clear the bar for verifiable company substance beyond a bare IEEE registration; treat the vendor identity as Likely rather than Confirmed pending a single first-party corporate site.
