The Developer Tags, used in both the Enterprise and Creator systems, come delivered with a 1200 mAh power bank. In Creator mode, developer tags use 180 mAh. Creator Kit tags and anchors both use about 180 mA at max update rate, regardless of voltage. You can connect a battery of 3.3 to 9 V to the DC jack, use the 5 V pin or the micro USB port to power your Pozyx device (tag or anchor – but anchors do not have a 5 V pin). Alternatively, you can also connect a 3.3 V battery to the VDD pin. Do NOT power Pozyx products directly on the VDD pin with over 3.3 V as this pin, as well as the 3.3 V pin, bypass the voltage regulator and your device will break if a voltage over 3.3 V is supplied here. When the tag is connected to an Arduino Uno board as a shield, you can power the Uno board with a 5 to 12 V battery.
