Ease of Development: Supports Linux-5.10.209, Ubuntu 20.04, Node-Red, Qt-5.15.2, and Docker, simplifying application development.
Reliable Design: Fanless aluminum alloy casing, DIN35 rail mounting, 9-36V wide voltage input with reverse polarity and overcurrent protection.
These features make the BL410 series particularly suitable for real-time monitoring, data processing, and remote management in smart vending machine.
Smart vending machine (e.g., cold chain cabinets) require real-time monitoring of temperature, humidity, and door switch status to ensure product quality and device security. The BL410 series, with Y-series I/O boards (e.g., Y51 for PT100 temperature sensors, Y01 for 4 DI/DO), can collect environmental data and switch signals. Combined with the 1TOPS NPU, it enables local analysis to quickly detect anomalies (e.g., temperature out of range) and trigger alarms.
Distributed smart vending machine require remote monitoring to reduce manual maintenance costs. The BL410 supports 4G modules (BL412L model) and WiFi (BL412W model), with BLIoTLink software enabling Modbus, MQTT, OPC UA, and other protocols to upload inventory, sales, and fault data to cloud platforms. The BLRAT remote access tool simplifies device maintenance, supporting firmware updates and fault diagnosis.
The BL410’s optional HDMI 2.0a interface (supporting 4K@60fps display) combined with Qt-5.15.2 enables the development of touchscreen interactive interfaces for displaying product information or advertisements. X-series I/O boards (e.g., X23 with 4 RS232/RS485) can connect to QR code scanners or NFC modules, supporting cashless payments and enhancing user experience.
By connecting cameras (via USB or HDMI), the BL410 leverages its NPU to run facial recognition or customer flow analysis algorithms, identifying user characteristics and delivering personalized advertisements. This AI capability is particularly suitable for unmanned vending machines, enhancing marketing effectiveness and theft prevention.
The BL410 supports Node-Red for rapid development of inventory monitoring applications. Through DI/DO interfaces, it detects product pickup or placement status, and integrates with cloud platforms (e.g., Alibaba IoT) for real-time inventory management and sales data analysis, optimizing restocking strategies.
Efficient Edge Computing: The quad-core Cortex-A55 processor and NPU provide robust computing power, reducing cloud dependency and latency.
Flexible Scalability: X/Y-series I/O boards support a wide range of sensors and communication interfaces, meeting the needs of cold chain, delivery lockers, and other scenarios.
Stability and Reliability: Passes EMC tests (ESD Level III, EFT Level III) and environmental tests (-40°C to 85°C, IP30), ensuring long-term stable operation in harsh environments.
Ease of Development: Support for Node-Red, Python, Qt, and Docker lowers development barriers and accelerates application deployment.
Low Power and Cost Efficiency: The ARM architecture’s low power consumption (9-36V wide voltage input) reduces energy costs, and modular configuration lowers hardware expenses.
