Applications
【1】 High performance industrial controller with sufficient computing power
STM32F407ZGT6168MHz main frequency, large capacity on-chip Flash/RAM, comparable to small PLCs; Support multi task scheduling, complex logical operations, and simultaneous parsing of multiple protocols. Both bare metal and FreeRTOS can run stably, and the industry will not experience frame drops or lag for a long time.
【2】 Dual Ethernet ports, dual scheme redundancy
W5500 hardware TCP/IP: protocol stack hardware solidification, does not occupy MCU resources, strong anti-interference, stable networking, suitable for Modbus TCP, industrial transparent transmission, and fixed protocol industrial control scenarios. LAN8720 external PHY: Paired with STM32 native MAC, it can run LWIP, customize network protocols, and interface with HTTP/MQTT/IoT platforms, with extremely high flexibility in secondary development. Dual network can be used for isolated networking, primary and backup redundancy, and one network for data collection and transmission, suitable for complex industrial sites.
【3】 Fully equipped industrial communication interfaces, no additional expansion required
Integrated RS485+CAN+RS232 three major industrial standard interfaces:
RS485:ModbusRTU、 Networking of frequency converters, instruments, and sensors
CAN bus: CANopen, vehicle communication, multi device bus linkage, industrial distributed control
RS232: A board that covers the vast majority of industrial control communication needs, including old-fashioned industrial control equipment, serial port printing, upper computer debugging, and serial port peripheral docking.
【4】 Standard PoE power supply, simple and worry free wiring
Supports standard Ethernet PoE power supply, allowing one Ethernet cable to simultaneously power and transmit data without the need for additional power cords; Compatible with PoE switches and PoE modules, suitable for installation and wiring in computer rooms, weak current boxes, outdoor sites, and wall mounted equipment.
【5】 Dual USB interface, combining debugging and peripheral expansion
Type USBSlave: firmware download, virtual serial port debugging, upper computer communication, no additional downloader required.
USB AHost: Can connect USB flash drives, keyboard and mouse, USB peripherals, achieve offline log storage, data export, and peripheral expansion.
【6】 Multi layer storage architecture ensures data retention without loss
W25Q64: Store font library, firmware, interface resources, and operation logs
AT24C02: Save device parameters, address, calibration values, and configuration information in case of power failure
MiniTF card slot: expandable large capacity storage, local historical data, file cache, offline upgrade
【7】 Comes with built-in display and human-computer interaction, ready to use out of the box
10P standard SPILCD direct insertion interface, compatible with ST7735/ST7789 serial LCD screens, can be used for Chinese UI, parameter settings, status display, and device dashboard; Onboard user buttons+LED, supporting manual configuration, operation/fault status indicator lights.
【8】 Compatible with PLC industrial control shell, industrial finished product
The board is compatible with the universal PLC standard housing, supports DIN rail buckle installation, has an industrial neat layout, strong and weak electrical separation, strong anti-interference ability, and can be directly used as commercial controllers and complete equipment without additional structural design.
【9】 Low development threshold and strong reusability
All peripheral hardware has been pre installed, eliminating the need for self drawing boards and building peripheral circuits; Rich routines and wide protocol compatibility greatly shorten the project development cycle, suitable for personal research and development, enterprise secondary development, and batch OEM.
