Neousys MezIO-V21 Ignition Power Control MezIO Module with PCIe and USB Mini PCIe Socket

Mini PCIe cards come in two kinds: those that use the USB lines in the socket and those that need a PCIe link. In a vehicle computer with one spare position, it helps if that socket can take either. The MezIO-V21 is part of the Neousys MezIO-V20/V21 series of ignition power control MezIO modules, and its full-size mini PCIe socket carries both PCIe and USB 2.0, with a SIM socket alongside for a cellular card.

The module provides ignition power control with predefined power-on and power-off delay modes, selected on a rotary switch on the rear panel, and an ultra-low 12 mA standby draw with the ignition off. Low-battery protection shuts the system down if the input stays below 11 V on a 12 V supply or 18 V on a 24 V supply for 60 seconds. Guarded delays cancel a start or shutdown if the ignition changes back, and a system hard-off cuts power 10 minutes after the off delay if a soft shutdown fails. Where a USB-only socket is enough, the MezIO-V20 pairs the same ignition control with a USB 2.0 mini PCIe socket.

We fit the MezIO-V21 inside the Neousys system on its high-speed board-to-board connector with three-point mezzanine mounting, install any mini PCIe card you specify, set the ignition delay mode and test the build before it ships. There is one MezIO interface per system. The MezIO-V21 fits the POC-900, POC-700, POC-700-FT and POC-600 compact computers, and the Nuvo-9000LP and Nuvo-11000LP computers.

For Nuvo computers that need ignition control without a mini PCIe socket, the MezIO-V20-EP is the matching module. Send us the vehicle supply voltage, where the ignition signal is taken from and how long the system should stay on after the engine stops, and we can suggest a delay mode and check the wiring before we build.
