2. Core Hardware Technical Specifications

2.1 Display & Lightweight Body Construction

- Screen: Color TFT display optimized for clear real-time ECG waveform rendering and daily fitness data viewing. Unlike basic fitness trackers, this panel adjusts contrast to render faint ECG curves clearly under indoor and outdoor light.

- Housing material: Lightweight PC plastic shell that cuts down overall weight for all-day comfortable wear.

- Net weight: 22 g excluding straps to minimize wrist pressure during multi-hour continuous health monitoring sessions.

- Standard straps: Interchangeable multi-color TPU and silicone sweat-resistant bands that match casual, sport and office daily outfits.

- Waterproof limitation: Aftermarket metal and leather straps carry no water-resistant sealing layers. Users must swap back to original silicone/TPU straps before any water contact to avoid internal sensor damage.

2.2 Connectivity & Built-In Biometric Sensor Modules

- Transmission: Low-power BLE Bluetooth module that maintains stable continuous data sync between bracelet and paired mobile device.

- System compatibility: Works with Android 8.0 or newer, iOS 9.0 or newer, and fits all mainstream consumer smartphone models on the market.

- Core health hardware: Combines single-lead ECG electrode sensor + PPG optical heart rate sensor to run dual-channel biometric sampling at user-triggered or scheduled intervals.

- Offline storage: The bracelet holds temporary heart rate, SpO2 and sleep data locally. Once Bluetooth reconnects, it uploads complete ECG waveform records to the mobile APP cloud storage automatically.

- GPS limitation: This bracelet carries no standalone GPS sensor. For that reason, outdoor sport route mapping fully depends on paired smartphone GPS signals within the supporting mobile APP.

- Function limitation: This bracelet omits built-in microphone, speaker and Bluetooth call hardware, so it focuses purely on health and activity tracking rather than communication features.

2.3 Battery & Cable-Free USB Direct Charging Performance

- Battery specification: Small-form lithium polymer cell that matches the bracelet’s low-power health monitoring hardware layout.

- Charging design: The detachable strap structure exposes an integrated USB male plug, so users skip separate proprietary charging cables and plug the unit straight into standard USB ports.

- Standard input requirement: Accepts 5V/1A universal USB power supply, including power banks, laptop ports and wall adapters for flexible charging scenarios.

- Full charge duration: Needs 2 continuous hours under standard 25℃ laboratory test environment to reach full battery capacity.

- Lab-verified runtime: Delivers 5–7 days of mixed daily usage with routine ECG sampling and moderate notification alerts enabled.

- Runtime note: Frequent manual ECG waveform recording and high-frequency push notifications drain power faster and shorten actual battery endurance in daily use.

- Circuit protection: Integrates overcharge, over-discharge and short-circuit prevention hardware to stabilize long-term uninterrupted health monitoring operation.

2.4 3ATM Waterproof Performance (ISO 22810:2010 Standard)

The VO203 follows the international ISO 22810:2010 3ATM water resistance standard. As a result, it blocks daily handwashing splashes, perspiration and brief shallow cold water contact during regular daily activities.

The following activities create permanent internal hardware damage and void the factory’s full hardware warranty: diving, snorkeling, high-pressure water jet cleaning, prolonged swimming, hot water bathing and sustained sauna steam exposure.

Internal rubber sealing gaskets undergo natural material aging with daily wear. Over months of regular use, this process gradually weakens the device’s splash and sweat resistance performance.

3. Dual ECG + PPG Professional Health Monitoring Functions

Disclaimer: All ECG waveforms, heart rate, HRV, SpO2 and sleep cycle data generated by this bracelet serve only as consumer-level daily lifestyle reference. This wearable is not FDA or clinical medical grade diagnostic equipment and cannot replace hospital ECG machines or professional medical testing devices. It is not intended for clinical diagnosis, disease assessment or medical treatment guidance. Users experiencing persistent chest tightness, palpitations or abnormal physical symptoms must consult a licensed medical practitioner immediately.

Biometric reading accuracy shifts based on strap tightness, arm hair coverage, wrist tattoos, skin surface condition and ambient temperature. The bracelet hits over 97% baseline heart rate detection accuracy under standardized laboratory testing conditions.
