11Mbps: -82 dBm Antenna Connector: 1 x RP-SMA CAUTION! The Digi Connect ME and Digi Connect Wi-ME embedded modules were designed for use in no clean flux wave soldering processes. The product is not designed to support draining after a water-wash process, which can lead to water residue inside the enclosure resulting from direct entry or condensation after the wash process. -
Page 41: Data Rates (Bps)
— — CAUTION! The module’s +3.3V (pin 15 for Digi Connect ME 9210 Family and pin 9 for Digi Connect Wi-ME 9210 Family) has the equivalent of a 500uF capacitor connected between it and GND. At power on, this equivalent capacitance will cause an input inrush current that is dependent on the voltage rise time of the user supplied +3.3V power source. - Page 42 (3657.60 meters) 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.
