OrangeLink is a compact smart converter that bridges 433 MHz / Sub-1GHz RF, Bluetooth Low Energy and NFC into a single, developer-friendly module — so legacy RF devices, phones and cloud apps finally speak the same language.
Modular middleware for smart home, IoT, access control & industrial telemetry.
Most wireless ecosystems can't talk to each other — 433 MHz remotes, BLE wearables and NFC tags live in separate worlds. OrangeLink sits in the middle as intelligent middleware, translating between them in real time so you can integrate any device into your app, hub or cloud.
OOK / ASK / FSK / GFSK transceiver covering 433, 868 and 915 MHz bands for long-range, low-power links.
Acts as a BLE gateway so phones and tablets can read and control devices that were never Bluetooth-enabled.
ISO 14443 read / write for tap-to-pair, access control and secure identification.
On-device middleware translates frames between protocols with sub-millisecond latency — no cloud round-trip needed.
Clean UART / USB-C interface with a documented API and cross-platform SDK. Integrate in hours, not weeks.
Optimized for always-on operation and embedding into hubs, gateways and OEM products.
Bring legacy 433 MHz sensors, switches and remotes into modern BLE / app-based smart-home ecosystems without replacing hardware.
Tap-to-unlock, secure pairing and identity for doors, lockers and shared devices using the built-in NFC frontend.
Collect data from Sub-1GHz field sensors and relay it to BLE handhelds or gateways for maintenance and monitoring.
A single tool to sniff, bridge and test multiple wireless protocols — ideal for engineers and product teams.
