Warning: The rise time of the 3.3v power supply must be between 700  S and 140ms
and the inrush current must be limited to less than 2 A. A rise time outside of these
limits may cause the device to malfunction and give a 3-1-3 diagnostic error.
Note:
Grounding Recommendation
It is recommended that you connect the tabs on the chassis of the Digi Connect ME / Wi-
ME, and the ground pins directly to the logic ground plane. It is also recommended that you
connect the Digi Connect ME / Wi-ME to the metal chassis of your enclosure. The idea is
to provide the shortest path or a path away from circuitry for ESD to travel to ground.
The embedded modules provide an on board supervisor circuit with a 2.93V
(nominal) reset threshold. When VCC falls to the threshold voltage, a reset pulse is
issued, holding the output in active state. When power rises above 2.88V, the reset
remains for approximately 250 ms to allow the system clock and other circuits to
stabilize.
