3.5" Subcompact Motherboards
The 3.5" Subcompact form factor (146 x 102 mm) is one of the most popular standards among industrial single board computers (SBC). It offers an excellent balance by combining compact dimensions with rich I/O (Input/Output) ports.
This size provides an ideal solution for applications where space is critical but require multiple COM ports, LAN, and USB connections. Equipped with low power consumption processors that allow for fanless designs, these boards form the backbone of many embedded systems such as industrial automation, kiosks, HMI panels, and digital signage displays.
