MezIO Modules
MezIO I/O Modules for Rugged Embedded Computers
A MezIO module adds application I/O inside a compatible rugged embedded computer, on a mezzanine board that mounts on the motherboard instead of taking an expansion slot. It turns a general-purpose box PC into a controller with the serial, digital I/O, network or vehicle power functions the job needs.
Options include isolated digital I/O, multi-mode serial ports, Gigabit Ethernet with PoE+, USB 3.1, a 2.5 inch drive bay and ignition power control, suited to factory automation, machine vision and in-vehicle systems where every port has to sit inside one rugged enclosure.
Speak to a MezIO specialist to match the module, its cabling and the host computer to your system.

MezIO Module Ranges Configured by Things Embedded
We work with the leading manufacturers of rugged embedded computers, so the MezIO ranges below are the ones we fit into Nuvo and POC systems. Compare them by I/O function, then browse the modules above or ask an embedded specialist which one suits your system.

MezIO-C180/C181 8-Port Serial Modules
Four multi-mode RS-232/422/485 ports plus four RS-232 or RS-422/485 ports, all on one 68-pin SCSI-II connector.

MezIO-D330 and D230/D220 Isolated DIO Modules
Isolated digital inputs and outputs at up to 24 V DC in 16 or 32 channels, with every channel on one 68-pin SCSI-II connector.

MezIO-G4/G4P Gigabit Ethernet Modules
Four extra Gigabit Ethernet ports on Intel I210 controllers, with 802.3at PoE+ on the G4P for cameras and sensors on PoE+ builds.

MezIO-U4 USB 3.1 Modules
Four USB 3.1 Type-A ports, with 5 Gbps on every port on the U4-50 and bandwidth shared between port pairs on the U4-30.

MezIO-R11/R12 Storage Modules
A 2.5 inch SATA drive bay inside POC computers, with four isolated inputs and four isolated outputs added on the R12.

MezIO-V20/V21 Ignition Control Modules
Ignition power control with predefined power-on and power-off delays for 12 V and 24 V vehicles, with a mini PCIe socket on the V20 and V21.
