Page 11: Hardware Feature Configuration
EK-AI7933ALD 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-AI7933ALD, 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. - Page 12 Table 1 Jumper settings for system power input through USB connection Jumper Usage Comments Use external power source to supply 5V voltage to EK-AI7933ALD External 5V power supply PCB. Pin 1 is 5V source. Pin2 is GND. DC-5V transfer to DC-3V3 current...
