Electrical Characteristics
The Module input power voltage is brought in on the ten VDD_IN pins and returned through the numerous GND pins
on the connector. A Module will withstand an indefinite exposure to an applied VDD_IN that may vary over the 4.2V
to 5.25V range, without damage, and it will operate over the entire VDD_IN range of 4.2V to 5. 25V.Ten pins are
allocated to VDD_IN. The connector pin current rating is 0.5A per pin. This works out to 5A total for the 10 pins.
