3.4 ECU - M30x
Note: This section applies to the M30x module ECU only. If you are designing for an M31x
module, please refer to the M31x ECU discussion that follows this section.
The M30x ECU dimensions are shown in Figure 11. The ECU should be placed in proximity
(both distance and orientation) to the sensor head to allow for proper installation and
routing of the flex cable that connects these two components of the M30x. The ECU is a
printed circuit board (PCB) with components on both sides. Wiring for power and I/O
interfaces are available at connectors, perpendicular to the PCB. Allowances for wiring
need to be made when considering the M30x ECU mounting strategy.
Figure 11: M30x ECU dimensions
The total ECU thickness with components and connector receptacles is 9.17mm. The
connector side thickness is 5.6mm with respect to the PCB surface and the shield side
thickness is 2mm with respect to the PCB surface. The PCB itself is 1.59mm thick. As with
the sensor head, a complete 3D model is available from Lumidigm to facilitate mechanical
design elements of the customer enclosure required to capture and secure the M30x ECU.
