AI Core module
A detachable AI core — not just a watch
The AI Core integrates the MCU, audio, camera, display, connectivity, power and haptics, and connects over a magnetic Pogopin interface to wrist, desktop, in-car and charging docks.
- E-paper display (non-touch)
- Front camera
- Microphone array
- Mainboard (4-layer PCB)
- Battery (150–300 mAh)
- Magnetic back cover · Pogopin interface · optical coupling area
Multi-scenario docks
One core module, many ways to wear and mount it
The same AI Core moves between wrist, charging, desktop, car and home docks over an 8-pin magnetic Pogopin interface.

From everyday assistant to field terminal
Personal Everyday AI
An AI assistant you actually carry
S1 enters a conversation straight from the physical AI Button or voice, with the e-paper display carrying status and summaries — voice input, image capture and interruption without occupying your hands.
Mobile Work
Capture and summarise on the move
Voice memos, meeting summaries and task generation turn spoken information into structured content, synchronised across devices.
Home & Desktop
An AI entry point for desk and home
Desktop and home docks turn the AI Core into a resident service entry point, using e-paper and the light bar for low-interruption status, with dual microphones and acoustic design improving real-world recognition.
In-Car
In-car voice, with agent continuity
The car dock lets the same AI Core keep serving inside the vehicle — voice-first with physical interruption, and context that follows the person rather than the device.
Industry
A lightweight terminal for field work
For inspection, field notes, after-sales service and sales support: lightweight capture through voice and photo recognition, with modular docks adapting to how each role wears or mounts the device.

FAQ
What people ask about S1
What is S1?
S1 is an AI Agent personal entry terminal developed by sigelang Technology (Shanghai) Co., Ltd. It consists of a detachable AI Core module and a range of scenario docks. The AI Core carries an e-paper display, dual microphones and a front camera, and you interact with the AI agent through voice and vision.
How is S1 different from a smartwatch?
A smartwatch is usually built around a touch screen and health tracking, with AI features layered onto that existing form. S1 is designed around the AI agent instead: it uses a low-power non-touch e-paper display, takes voice and vision as its primary inputs, and its core module detaches from the wrist strap so it can continue running on a charging, desktop, car or smart-home dock.
How do the AI Core and the docks relate?
The AI Core is the module that holds the compute, the interaction hardware and the battery. A dock provides mounting, power and scenario-specific adaptation. They connect through an 8-pin magnetic Pogopin interface on the back of the AI Core. Five docks are planned: Watch Dock, Charging Dock, Desktop Dock, Car Dock and Smart Home Dock.
What are the dimensions and weight of S1?
The AI Core module measures 45×38×12 mm, weighs about 36 g and carries a 150~300 mAh battery.
Which SoC and display does S1 use?
S1 uses an ESP32-S3-WROOM-1U as its main controller and a low-power non-touch e-paper display. Audio consists of dual MEMS digital microphones with a MAX98357A I2S amplifier and a side-firing speaker, and a front camera sits at the top centre of the front face.
What connectivity does S1 support?
S1 supports Wi-Fi, Bluetooth and cellular. Cellular connectivity lets the AI Core stay online independently, without tethering to a phone.
How do you wake and operate S1?
S1 has an AI Button flush with the top edge of the housing. A short press starts a conversation with no unlocking or app switching. An RGB light bar indicates state and a haptic engine provides tactile feedback.
What is Holoyo?
Holoyo is the AI assistant persona and wake word on S1. It handles voice conversation, note capture, reminders and image recognition.
Can I buy S1 today?
Not yet. The project is at the DVT-ready EVT engineering-validation stage and is not in mass production, so no pricing or delivery timeline is available. Channel partners, industry customers and supply-chain collaborators are welcome to contact us through the enquiry form to join prototype validation.
