The adapter on-board's peripherals are powered with 3.3V as supply voltage. If 3.3V and VIO is supplied only by the on-board LDO DCDC converter U3 (switches S2-3 and S2-4 ON), the I/O-pins of header J2 deliver max. XMOD adapter board has max. output current of ~100mA.
If module is powered from base then S2-4 (and most likely S2-3 (VIO) too) must be OFF.
Following diagram shows how the settings of the DIP-switches S2-3 and S2-4 determines the configuration of the on-board voltages:
