Key Highlights: Industrial-grade configuration + maker-level convenience, a must-have final product.

As the final product in this video series, StamPLC perfectly combines the professionalism of industrial-grade PLCs with the "out-of-the-box" core advantage of M5Stack products. Its six key highlights make it an ideal choice for automation development and a "stepping stone" for makers to enter industrial-grade projects:

• Dual-core architecture : Stamp-S3A control module + PLC dual core, equipped with ESP32-S3 chip, combining industrial-grade processing capabilities with efficient wired / wireless connection, stable operation without lag;

• Full range of industrial control interfaces : 8- channel optocoupler isolated input, 4- channel relay output, and full coverage of CAN/485 industrial bus interface, making sensor and actuator connection simple and reliable without the need for additional adapters;

• Harsh environment adaptability : 6-36V wide voltage power supply, DIN rail mounting + multiple fixing methods, easily cope with complex industrial environments, and ensure stable operation ;

• Cloud-based remote management : It connects to the EZData cloud platform by default, automatically generates monitoring pages, and enables one-click remote access and centralized control without the need to manually build a backend.

• Open source ecosystem compatibility : Adapts to Home Assistant , supports rich API interfaces, integrates into a wide range of open source IoT ecosystems, and has unlimited scalability;

• Maker-friendly design : Continuing the convenient development concept of M5Stack , the visual operation and simple programming make it easy for beginners to get started quickly, breaking down the professional barriers to industrial control development.

Product Details: Comprehensive and powerful configuration, balancing professionalism and convenience.

StamPLC can be a "versatile partner" for industrial automation and maker development because of its core hardware configuration tailored for automation scenarios. From core architecture to interface design, from environment adaptation to human-computer interaction, every aspect takes into account industrial professionalism and ease of development, demonstrating the strength of the final product.

Dual-core converged architecture, with processing and connectivity both online.

The product name StamPLC contains a hidden core code, composed of two parts: " stamp " and " PLC ." " Stamp " represents the Stamp-S3A control module based on the Espressif ESP32-S3, while " PLC " is an abbreviation for a classic programmable logic controller. This powerful combination not only provides equipment with robust industrial-grade processing capabilities but also enables efficient wired and wireless dual connectivity. It meets the stable operational needs of industrial scenarios while adapting to the remote connectivity requirements of the Internet of Things era, laying a solid foundation for automated control and data transmission.

Full coverage of industrial control interfaces, making expansion and integration extremely worry-free.

In terms of control and expansion, StamPLC achieves comprehensive industrial-grade coverage: equipped with 8 optocoupler-isolated digital inputs , 4 relay outputs supporting AC and DC loads , plus 2 HY2.0-4P interfaces and side expansion pin jacks, various industrial sensors and actuators can be directly connected, eliminating the hassle of complex conversions; it also comes with PWR-CAN and PWR-485 interfaces , allowing the device to be seamlessly integrated into industrial fieldbus networks, easily realizing remote data transmission and centralized control, perfectly adapting to industrial-grade networking requirements.

Industrial environment adaptable, stable operation guaranteed

To cope with harsh industrial environments, StamPLC has undergone comprehensive hardware optimization: it supports a wide voltage range of 6 to 36V DC power supply , unaffected by voltage fluctuations and adaptable to different power supply scenarios; it is perfectly compatible with DIN rail mounting , and the product package includes 4 expansion parts with holes and 4 adjustment expansion parts. The back of the device also has 4 M3 screw holes and 1 wall-mounting hole, offering multiple installation options to ensure stable fixation in different scenarios; the built-in microSD card slot facilitates local storage of industrial data and convenient firmware updates, making equipment maintenance more worry-free.

Intelligent monitoring and interaction ensure both operation and early warning.

One-click cloud-based linkage, ultra-convenient remote control

Typical scenario: Easy implementation, unlocking endless possibilities for automated development

With its excellent hardware configuration and user-friendly design, StamPLC can easily adapt to various automation control scenarios, from simple environmental monitoring to complex remote equipment control. No extensive industrial control development experience is required for rapid implementation. Two typical scenarios will give you a direct feel for the power of this final product:

Intelligent environmental monitoring with real-time alarms for anomalies.

Connecting the StamPLC to the Unit ENV-III environmental sensor enables industrial-grade intelligent environmental monitoring. Taking humidity alarm as an example, after connecting the hardware to a computer, simply set the program logic in the Arduino : after connecting to Wi-Fi, read the sensor's humidity value in real time; when the humidity is greater than 80% , the device screen turns red, the buzzer sounds, and a notification is sent to the mobile phone. After compiling and uploading the code, this function can be implemented. Environmental monitoring in industrial sites and workshops can be handled with one click, safely and efficiently.

Remote actuator control, super simple visual operation

In addition to collecting sensor data, StamPLC can easily control various actuators, such as remote lighting control via its built-in relays. These operations do not require complex industrial control programming and can be completed directly in the device's factory firmware and the EZData web platform, offering a user-friendly and intuitive visual operation.

EZData platform configuration is also very simple: enter the device's Wi-Fi configuration mode, connect to the AP " M5StamPLC-WiFi-Config ", access 192.168.4.1 through a browser to configure the Wi-Fi information and save it. After the device restarts, enter the Monitor Link page, scan the QR code to access the remote control page and log in to the M5Stack account to achieve remote control. The whole process only takes a few steps and even beginners can easily do it.

Furthermore, StamPLC 's input channels integrate optocoupler isolation, supporting DC 5~36V high / low level signal input acquisition, adapting to different types of industrial sensors. It also provides more API interfaces, enabling richer functional interactions, and thanks to the efforts of community developers and engineers, it has been adapted to Home Assistant , allowing it to integrate into a wider open-source IoT ecosystem. Whether for home automation, personal studio projects, or industrial control needs in small factories, it can be perfectly adapted.
