Round Knob Display for Next-Gen HMI

Designed for the "Intuitive Control: Tri-Force Knob" philosophy, this module is more than just a component—it is a complete, IoT-ready control hub for smart environments.

★ Engineering Intuition: Why ST013A-M023?

Modern users demand simplicity. The ST013A-M023 delivers this through a multi-modal interaction model. Unlike traditional encoders, this device supports 360° rotation, touch gestures, and physical push commands, allowing developers to create layers of control that feel natural and responsive.
 

★Key Interaction Features:

360° Continuous Rotation: Smooth, tactile feedback for precise parameter tuning.

Multi-Gesture Support: Integrated touch panel supports short/long push, touch, and swipe gestures, enabling smartphone-like navigation on a rotary dial.

Visual Confirmation: The 240*240 resolution display provides instant, high-contrast feedback for every user action.
 

★Technical Deep Dive: Performance Meets Reliability

The ST013A-M023 is engineered to perform in demanding environments, from high-end kitchen appliances to rugged industrial panels. Below is a detailed breakdown of its technical architecture.

1. Processing Power & Connectivity

At its core, the module is powered by the RF2280 Internet SOC, a high-performance system-on-chip designed for the IoT era.

Wireless Intelligence: Built-in BLE 5.1 (Bluetooth Low Energy) ensures seamless connectivity with mobile apps and mesh networks.

Memory Architecture: Equipped with 64M eFLASH, 16M PSRAM, and 64K RAM, providing ample headroom for complex GUI transitions and data logging.

Expandable Storage: Default 64M storage can be expanded up to 512M SPI FLASH for resource-heavy applications.
 

2. Mechanical Precision (The "Tri-Force" Standard)

The "feel" of a knob determines the perceived quality of the entire product. We have optimized the mechanical specs to ensure a premium tactile experience:

Rotation Torque: 30-200gf.cm (adjustable feel for precision tuning).

Push Strength: Rated at 5Kgf.cm, ensuring durability even under heavy-handed use.

Compact Form Factor: A 46mm diameter makes it easy to integrate into existing faceplates and enclosures.
 

3. Display & Optical Quality

Clarity: 1.28" IPS-grade display with 240*240 resolution.

Brightness: 250cd/m², optimized for indoor clarity and power efficiency.

Glass Transmittance: ≥25% (Normal Black), providing a sleek, integrated look when the screen is off.

★Technical Specifications Summary

★ Versatile Applications: From Kitchen to Cockpit

The ST013A-M023 is a versatile powerhouse suitable for a wide range of industries:
