3.8 Extra Features
3.8.1 VLDO2 Power Measurement Connector
The ATSAMA5D27-WLSOM1 module embeds an LDO with capacities of:
• Output voltage from 1.2V to 3.3V by 50 mV steps
• Output current capability up to 300 mA
A 2-pin connector (J14), not populated by default, is available on the baseboard to measure output current capability
of the VLDO2 regulator.
Note: The maximum current available on VLDO2 node is approximately 300 mA max @ 1.2V to 3.3V.
