BCM notes that while most of the small form factor industrial motherboards with a wide range DC power design support 12V to 24V, the ECM-3455J 3.5-inch SBC supports a wider 9V to 36V DC input voltage, which makes it suitable for a wider range of embedded applications including industrial control, human-machine interface (HMI), digital signage, Point-of-Sale terminal, retail kiosk, medical and healthcare equipment, and so on.
BCM ECM-3455J 3.5-inch single board computer is shown as “coming soon” on the product page, so it’s not clear when it will become available, and pricing for this type of B2B board is often not made public. As a side note, BCM Advanced Research used to be (and probably still is) a subsidiary of Avalue, which we covered in the past with several other “ECM” boards.
