Hardware Entry × Intelligent Platform × Continuous Operations
The Lanka LC-1.7 is a standard AI module from Lancun designed for AI toys, interactive devices, smart home, educational terminals, and robots. It integrates voice, connectivity, sensing, control, and execution capabilities into a compact 36 × 36 × 22 mm structure, and works with the Lancun Intelligent Platform (Hardware AI Runtime) to complete agent configuration, device binding, real-device debugging, OTA, and continuous operations.
1. One Module, the Hardware Entry Point for AI Terminals
The Lanka LC-1.7 is designed around the four most critical capabilities in real terminal development: natural voice interaction, device connectivity, peripheral sensing and control, and connection to the cloud agent platform. Standardized hardware reduces the workload of rebuilding from scratch across main control, audio, network, interfaces, and firmware, allowing product teams to focus more on character, content, interaction, and product experience.
Compact size. The complete white-box is approximately 36 × 36 × 22 mm, fitting into compact structures such as plush toys, desktop ornaments, pendants, screen-equipped terminals, and small robots.
High adaptability. Reserved interfaces for screens, touch, sensors, motors, servos, and general communication allow peripheral combinations based on different product forms.
Easy debugging. USB Type-C supports flashing and debugging; devices can be bound on the platform, with real-time log viewing and OTA remote upgrades.
Operable. Models, personas, voices, memory, knowledge bases, skills, and quick replies can be continuously adjusted in the cloud, without fixing the product experience in hardware at once.
2. Compact Hardware Balancing Voice, Connectivity, and Expansion
| Capability Domain | LC-1.7 Current Product Configuration and Capabilities |
|---|---|
| Core Main Control | ESP32-S3R8, 8 MB PSRAM, 16 MB Flash |
| Audio Interaction | Standard version primarily uses dual microphones, supporting AEC echo cancellation, voice capture and playback, button or voice trigger, real-time interruption; single or multi-microphone solutions can be evaluated per project |
| Connectivity | 2.4 GHz Wi-Fi, Bluetooth, and Wi-Fi / 4G dual-mode switching; eSIM uses a soldered design, suitable for mobile and collision-prone scenarios |
| Screen and Interfaces | Supports 0.71-inch dual-eye screen and other screen solutions; provides USB Type-C, GPIO, I²C, SPI, UART, PWM, ADC, and other interfaces |
| Sensing Expansion | Can connect touch, temperature/humidity, light, human presence, air quality, motion, distance, gyroscope, Hall effect, and other sensors |
| Execution Expansion | Can connect lights, screens, motors, servos, and other actuators, forming a complete chain from natural language to physical actions |
The standard module provides a stable hardware foundation; the number of peripherals, structure, power consumption, and action combinations can be tailored based on the terminal product solution. Combinations of single microphone, dual microphones, screens, sensors, and actuators depend on the selected version and project design.
3. Natural, Smooth, and Continuously Optimizable Voice Interaction
LC-1.7 connects terminal-side microphones and speakers with cloud ASR, LLM, and TTS, forming a complete interaction loop of "hear—understand—respond—execute." The dual-microphone structure, AEC echo cancellation, and interruption capability enable more natural conversations in real-world usage environments.
Devices can start interaction via voice wake-up or button trigger, supporting listen-while-speaking, real-time interruption, boot greetings, voice reminders, idle conversation termination, and OTA online upgrades. Persona, reply length, speaking rate, tone, and voice can be continuously tuned on the platform, adapting to different interaction styles such as children's companionship, elderly care, educational Q&A, IP characters, and service terminals.
4. From Sensing to Execution, Bringing AI into the Physical World
The rich interfaces allow LC-1.7 to read the environment, touch, and device status, and also convert the agent's decisions into light, screen, sound, and action feedback. Product teams can use sensors to obtain temperature/humidity, light, touch, posture, distance, or motion information, and then control volume, brightness, display, motors, servos, and other actuators through device tools and firmware protocols.
This chain extends terminals from "just chatting" to "sensing, responding, and executing." For example, toys can give different feedback when picked up or touched, smart home terminals can read environmental information and control devices, robots can decompose natural language into action sequences, and screen-equipped devices can simultaneously display expressions, status, and content.
5. Emotional Interaction, Making Devices More Characterful Over Time
Lanka and the Lancun Intelligent Platform jointly handle character, persona, memory, touch feedback, actions, and sound effects. Terminals can combine touch speed, holding posture, and ambient volume to form emotional feedback; the same action can be presented in fast, medium, and slow levels with different amplitudes, frequencies, and durations, combined with sound effects, persona, and long-term interaction states.
Recent project validation has formed 9 levels of emotional feedback, personality development, memory priority, and action-emotion mapping mechanisms. Over 6 million frames of offline action data are used for action classification and combination. High-frequency action commands, after independent skill reinforcement, have achieved a project test execution success rate of over 95%. These capabilities allow the device's actions, tone, and long-term interactions to gradually form a consistent character performance.
Around real usage environments, the latest optimizations also cover dual-microphone recognition, filtering and anti-interference, audio and action priority, servo stability under low battery, and graded sleep. Deep sleep standby current has been reduced from approximately 120 mA to 6–10 mA, providing more stable battery life for battery-powered terminals.
6. Module + Platform, Completing the Full Chain from Configuration to Operations
The Lancun Intelligent Platform (Hardware AI Runtime) is responsible for turning the hardware entry point into a configurable, testable, manageable, upgradable, and operable AI terminal. Teams can create applications and agents on the platform, configure models, personas, voices, memory, knowledge bases, skills, tools, and quick replies, and then bind agents to real devices for debugging.
The standard onboarding process is as follows:
- Create an application, defining the product name, codename, and business boundaries.
- Create an agent, configuring ASR, LLM, TTS, persona, voice, memory, knowledge base, skills, and tools.
- First, complete text or voice tests in the cloud to verify character and model effects.
- Complete device binding via verification code, MAC address, or project configuration.
- On the real device, check network, authentication, audio, recognition, playback, sensors, and action chains.
- After launch, continuously manage and update through templates, device lists, real-time logs, and OTA.
The platform supports multiple agent templates and sub-agent synchronization. The same product family can reuse unified persona, model, voice, and skill configurations, while retaining personalized parameters for different SKUs, characters, and users, significantly reducing multi-device operational costs.
