Lower Power & THIN Mini-ITX Design for CNC-HMI



 At automated production plants, the human–machine interface (HMI) of a computer numerical control (CNC) router serves as an interface between the operating system and human operator. It provides controls for users to operate machines, systems, and instruments. It also ensures reliability in the data processing operations of machining centers and can visualize the key control data from processes in real time. 

Requirements and Solution

One of our Chinese customers, a manufacturer of CNC routers used in various industries, was looking for a motherboard for a panel/software HMI solution for interacting with the CNC routers in order to improve operational efficiency and minimize downtime. Because the customer’s CNC routers were required to operate continuously, the customer needed a reliable motherboard with low power consumption for closely monitoring production and responding to changes in production demands. Furthermore, the customer required an API to act as a hardware–software bridge so that the system status could be monitored remotely and system data (e.g., CPU temperature, fan speed) could be collected for failure prediction and analysis. To meet these requirements, the Advantech AIMB-215 was selected as the HMI solution.    

Equipped with an Intel® Celeron® J1900 SoC, the AIMB-215 is an industrial-grade motherboard that offers low power consumption but high performance, and it supports dual independent displays for dual-channel 24-bit LVDS, VGA, and DisplayPort 1.2. The AIMB-215 has two onboard Mini-PCIe sockets and offers flexibility for users to implement mSATA for data storage or Wi-Fi, 3G, LTE solutions for data acquisition or transfer to the cloud. As a THIN Mini-ITX, with its 40%–45% reduction in height compared with Mini-ITX, low-profile I/O design, robust thermal solution, and Advantech’s customized SUSI API for Linux support, the AIMB-215 is the perfect fit for HMI applications.  

AIMB-215 Features

  • THIN Mini-ITX (height, <22 mm) 
  • Fanless design 
  • Supports dual displays: VGA, dual channel 24-bit LVDS, DisplayPort 1.2. 
  • Rich expansion options: two Mini-PCIe sockets (F/S x 1, H/S x 1 with SIM card holder)
