Note:

1. SYS_3.3V: 3.3V power output. In our test the real output was 3.1V
2. VDD_5V: 5V power input/output. The input range is 4.7V ~ 5.6V. It can take power input from the MicroUSB or the VDD_5V pin from the Debug Port. The VDD_5V is connected to MicroUSB's VBUS
3. All pins are 3.3V(In our test the real output was 3.1V), output current is 5mA
