    EK-AI7933CLD supports two types of power supply. 1) Power up with a micro-USB connector. An on-board switching regulator provides voltage of 3.3V for the EK-AI7933CLD, if the power is supplied from an on-board micro-USB connector CON8 (Figure 2). This supply can be isolated from the switching regulator using the jumpers.
