RTC:

3.35uA@3V

USB 2.0 Host:

with 1A over current protection

Note:

1. SYS_3.3V: 3.3V power output
2. VDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB’s the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.5V
