Solution for Smart Silence Pods / Mute rooms

Solution for Smart Silence Pods / Quiet Call Boxes control

PD.Screen_PRO + PD.Multicontroller + PD.AC_switcher = control all the functions of  the Silence Pod from a single Touch Screen

Designing modern Silence Pods requires more than acoustic performance — it requires fast development, secure connectivity, and seamless integration into smart building ecosystems. Our 7-inch / 10-inch touch screen module with special peripheral controller and AC load switcher board are designed to help Silence Pod manufacturers accelerate time-to-market while delivering advanced control and a premium user experience.

PD.Screen_PRO : smart touch-screen MCU computer with a lot of peripherals onboard

PD.Multicontroller : industrial-grade controller for Fans, RGBW LED strips, Locks, power IN/OUT, etc.

PD.AC_switcher : 2x 110V / 230V AC control and monitoring channels (up to 15A switching per channel) to create different scenarios with additional services inside the Pods (massage chair enabling, heater, big TV, coffee machine unlock, etc.)

Faster Time-to-Market with a Ready-to-Use MCU Platform

At the core of the Touch Screen (PD.Screen_PRO) module is a user-accessible ESP32 MCU, enabling rapid application development without proprietary tools.

• ESP32 Available for User Applications:
  Implement control logic directly on the ESP32 using familiar development workflows.

• Extensive Arduino Example Library:
  We provide ready-to-use Arduino examples, significantly reducing development time.

• Multiple Development Environments Supported:
  Full support for Arduino, PlatformIO, and other easy-to-use software ecosystems.

This approach allows manufacturers to move quickly from prototype to production.

Powerful Dual-MCU Architecture in the core – Simplified for the User

The module combines performance with simplicity through a dual-MCU design:

• ESP32 – Application & Connectivity MCU

• High-Performance STM32 – Graphics & Touch Processing MCU

All complex graphics and touch handling are managed internally by the STM32. The user interacts with the display using simple, high-level API commands from the ESP32—no advanced graphics programming required.

Native Control of Core Pod Functions with PD.Multicontroller

• 4x PWM Fan Control for precise ventilation and noise optimization
• 3x RGBW LED rails for Interior Lighting Control with dimming and scene support
• 1x Stepper Motor Driver Support for motorised vents, blinds, or doors
• 2x electromagnetic locks drivers for doors and shelves access control
• 12x power IN/OUT for different sensors (Temperature, Weight, Contact, etc.)

Industrial Interfaces for Maximum Expandability

• RS485 Interface for robust communication with external controllers, sensors, and BMS systems
• I²C and UART Interfaces for easy connection of additional controllers, sensors, or custom electronics
• QR-barcode scanner (1D and 2D) for paid access or interactive settings loading from the phone screen
• Modular system architecture that supports future feature expansion without hardware redesign (GPIO expansion slots on the back side of the module)

Built-In MQTT & Secure Cloud Connectivity

To support connected and smart-building-ready Silence Pods, the module includes native MQTT support on the ESP32:

• MQTT Communication Examples Provided:
  Ready-to-use Arduino examples demonstrate how to publish and subscribe to pod data such as fan status, lighting state, sensor values, and usage information.
• Secure MQTT (MQTTS / TLS) Examples Available:
  We provide examples for encrypted and authenticated MQTT communication, enabling secure integration with cloud platforms and enterprise systems.
• Ideal for Smart Buildings & Fleet Management:
  Enable remote monitoring, analytics, predictive maintenance, and centralized control of Silence Pod installations.
