I unloaded it and it now outputs 4.9V. The stat pin is still 0.7V though and the IN2 pin is 0.5V (not connected).
I found out that I possibly have a malfunctioning TPS63001. If the input is ~2.6V the board uses 300mA, when the input is 5V it uses 200mA but if the input s 3.3V it uses way over 600mA..?
