One Smart Controller. Total Control of Fans, Lighting, Locks, and Sensors.

PD.Multicontroller is a powerful peripheral control module designed for professional applications where reliable multi-channel control and sensing are required, designed for industrial applications with operational temperature range from  -30 to +70 deg C.

With RS-485, I²C, UART and USB connectivity, it integrates seamlessly into existing control systems, HMIs, PLCs, and embedded platforms.

Whether you are building smart cabinets, kiosks, industrial enclosures, access-controlled systems, or custom automation, PD.Multicontroller replaces multiple boards with one compact, intelligent solution ready to be implemented into ProtoDevs ecosystem.

Optimized for Low Power and High Reliability

At the heart of PD.Multicontroller is a low-power STM32 microcontroller from STMicroelectronics — one of the world’s leading manufacturers of industrial-grade microcontrollers. The STM32 MCU ensures:

Low power consumption for always-on systems

Deterministic real-time behavior

Stable operation across industrial temperature ranges (-30 … +70 deg C)

Robust handling of multiple control and sensing tasks simultaneously

This allows PD.Multicontroller to manage fans, LED lighting, locks, switching outputs, and sensors without performance compromises.

PD.Multicontroller is delivered with fully developed, production-ready firmware.

There is no need to write low-level firmware or manage complex peripherals.
All functions are already implemented and tested, allowing you to focus on system logic and user experience instead of embedded development by utilizing the API.

All features of PD.Multicontroller are accessible through an easy-to-use command-based API over: RS-485, I²C, UART, USB. Custom interfaces could be added. Remote Firmware updates supported.

Key Features at a Glance

Flexible Communication Interfaces

  • RS-485 – robust long-distance industrial communication

  • I²C – ideal for embedded controllers and SBCs

  • USB – fast configuration, diagnostics, and connection to PC/Tablets

Advanced Fan Control (4 Channels)

  • Supports 5V / 12V / 24V fans
  • Speed (RPM) feedback for real-time monitoring
  • Ideal for: thermal management, smart enclosures,s erver or cabinet cooling
  • Detect fan failure and control airflow intelligently

RGBW LED Strip Control (2 Channels)

  • Independent control of RGBW LED strips, high-current design supports 5V RGBW LED matrixes (up to 10A)
  • Smooth color mixing and brightness control
  • Perfect for: status indication,a mbient lighting, visual alerts and UI feedback

Electromagnetic Lock Control (2 Channels)

  • Direct control of 12V / 24V electromagnetic locks
  • Suitable for:
    • Access control systems
    • Smart doors
    • Secure cabinets and lockers
  • Designed for safe and reliable actuation

High-Power Switching Outputs (12 Channels)

  • 12 independent 12–24V switching channels

  • Drive relays, solenoids, lights, motors, and other loads

  • Sense Heating / Cooling, parcel weight, parcel presence, other sensors

  • Ideal for:

    • Smart Off-grid and On-grid parcel Lockers (for communities and for private sector)

    • Automation tasks

    • Actuator control

    • Power distribution

Each switching channel includes additional input pins for sensors:

  • Temperature sensors
  • Scales / load sensors
  • Door open / close detection
  • Other digital or analog sensors

This allows PD.Multicontroller to act not only as an output controller, but also as a central sensing hub.
