An Off-grid outdoor Platform for Automated Parking Access Systems

Modern automated parking systems require reliable access control, intuitive user interaction, secure connectivity, immediate ticket printing, and support for off-grid installations. Our 7-inch or 10-inch TFT touch screen module with embedded MCU is designed as a central control and HMI platform for parking access controllers, entry/exit terminals, and payment kiosks.

Accelerate Time-to-Market with a Ready-to-Use Control Platform

A Complete Parking Access Solution

By combining:

    • PD.Screen_PRO – control, HMI, connectivity, ticket printing
    • PD.Charger_GSM – solar power management, LiFePO₄ / Li-Ion battery charging, GSM & GPS
    • PD.Cam – low-power RS-485/I2C camera module for photo and video registering
    • PD.Motors_Board – low-power gate barriers driver with extended monitoring and remote firmware updates
    • PD.LoRa_Sensor – Ultra low-power parking space access detector

At the heart of the PD.Screen_PRO module is a user-accessible ESP32 MCU, enabling manufacturers to develop parking applications quickly using familiar tools.

    • ESP32 for User Applications
    • Extensive Arduino Example Library
    • Supports Arduino, PlatformIO, MicroPython & Modern Toolchains

This allows rapid prototyping and smooth transition from development to deployment.

Dual-MCU Architecture – Powerful Yet Simple

    • ESP32 – Application & Connectivity MCU
    • STM32 – Graphics, Touch & Display Control

All complex graphics and touch processing are handled internally. The user controls the UI using simple API commands, eliminating the need for advanced graphics programming.

Integrated Thermal Printer Interface

The module includes a direct interface for compact thermal printer modules:

    • Immediate printing of parking tickets, receipts, QR codes, and validation slips
    • No external printer controller required
    • Ideal for entry, exit, and payment terminals

Intuitive User Interface

The 7-inch / 10-inch TFT touch display supports:

    • Access guidance and system messages
    • QR-barcode scanners for access triggering
    • Ticket and payment confirmation visually and audially
    • Branded, customizable UI layouts

Native Control of Parking Hardware

    • Stepper motor driver for camera positioning
    • PWM outputs for signal lights and actuators
    • RGBW LED strip and indicator control for system status

Industrial Interfaces for Expansion

  • Enables seamless integration with parking management platforms, payment systems, and smart-city infrastructure.
    • RS-485 for barrier controllers and parking systems add-ons
    • I²C & UART for RFID, QR scanners, LPR systems, and sensors
    • Ethernet with PoE for fast integration into the existing LAN infrastructure
    • Wi-Fi & Bluetooth for MQTT & Secure MQTT (TLS) implementations

Solar-Ready & Off-Grid Parking Systems with PD.Charger_GSM

For parking installations where grid power is unavailable or impractical, we offer PD.Charger_GSM, a dedicated solar power management and connectivity module designed to work alongside the 7-inch / 10-inch PD.Screen_PRO touch screen controller.

Intelligent Solar & Battery Management

PD.Charger_GSM handles all power-related tasks:

    • Solar charging management with 2x MPPT inputs (up to 70V)
    • Embedded LiFePO₄ or Li-Ion battery charging and protection (up to 100 Ah+)
    • Optimized energy usage for 24/7 operation
    • Ideal for outdoor, roadside, and remote parking systems

Built-In Wireless Connectivity

In addition to power management, PD.Charger_GSM adds:

    • GSM connectivity for remote monitoring, alarms, and data transmission
    • GPS positioning for asset tracking, system identification, and fleet management
    • WiFi / Bluetooth for custom scenarios
    • LoRa / Sub-GHz for parking slots availability detection or custom sensors

    Manufacturers can build fully autonomous, solar-powered parking access systems with minimal external components.

    One Ecosystem. Multiple Deployment Scenarios.

    From grid-connected parking garages to solar-powered roadside installations, our modules provide a scalable, future-ready platform for modern parking access control—reducing engineering effort, shortening time-to-market, and increasing system reliability.
