IPH2331 NFC Passive Padlock PCBA NEW
Product Overview
The IPH2331 is a complete battery-free smart padlock PCBA solution consisting of a main control board and an NFC sensing board. A compatible smartphone supplies energy through its 13.56 MHz NFC field, so the lock electronics can authenticate a command and drive the geared motor without a battery inside the lock.
The platform combines NFC energy harvesting, regulated power, bidirectional data exchange, secure authorization, energy storage, and forward/reverse motor control. It is designed for OEM/ODM development of padlocks, luggage locks, lockers, storage cabinets, and other compact electronic-lock products.
Battery-FreeHarvests operating energy from a compatible phone's NFC field.
13.56 MHz NFCBidirectional communication compatible with ISO/IEC 14443A.
Secure AccessDevice UID verification plus a 64-bit rolling-code authorization scheme.
<3 s TargetFast unlock target under suitable antenna coupling and system conditions.
Dual-Board PCBAMain control board and dedicated communication/energy-harvesting board.
Custom AppAndroid, iOS, and HarmonyOS project support with multilingual UI options.
Place a compatible NFC phone near the sensing face. The sensing board harvests RF energy, rectifies it, and charges the onboard storage capacitors. After the power rail is ready, the phone and PCBA exchange authentication data. An approved command drives the motor forward to unlock or in reverse to reset the mechanism.

Integration & OEM/ODM
Mechanical and antenna co-design matter. The final sensing position, antenna matching, motor load, and energy thresholds must be validated in the assembled lock. Avoid metal, magnetic materials, and closed conductive loops near the NFC sensing face; phone cases and accessories can also affect coupling distance and unlock time.
Available project services include antenna tuning, motor and mechanism adaptation, firmware parameters, mobile-app branding, multilingual UI, connector definition, PCB layout adaptation, pilot builds, and mass-production validation.
Performance figures are development targets or prototype measurements from the V1.4 product documentation. Final specifications are subject to the approved hardware, lock mechanism, phone compatibility, and complete-product validation.
Two IPX1023 modules form a bidirectional wired intercom: each end connects a microphone and speaker, allowing both parties to speak and listen simultaneously. Neural noise reduction, acoustic echo cancellation (AEC) and anti-howling support voice communication. Start with a short cable, then validate the 50–100 m target using the intended wiring, grounding and site conditions.

AEC to reduce returned playback echo
Anti-howling for acoustic feedback control

System
2 modules with compatible hardware and firmware
Audio peripherals
One microphone and speaker per end; types and loads must match the board specification
Communication

Acoustic performance
Depends on components, gain and enclosure; verify double-talk, noise, echo and feedback in the complete system
Customization & Integration
Discuss microphone and speaker matching, enclosure acoustics, gain, algorithm settings, connector and harness requirements, hardware and firmware revisions, and sample acceptance. Supply voltage, current, audio loads and pinout must follow the delivered board specification. The illustrations are functional models, not a wiring pinout; an unidentified connector is not a USB, Ethernet or general-purpose RS-485 interface.
