),  1.8 V  (

1V8

),  and  selectable

voltages.  Power  supply for  the  EVB can  be provided  from the SDIO,  M.2  or  USB  host sockets  and 
internal DC-DC, or from external sources. The following power supply options are available on the EVB: 

 

SDIO or USB interfaces: The EVB is powered from the SDIO/M.2 or USB host sockets. All internal 
voltages are generated by DC-DC converters on the EVB. 

 

External sources: 3.3 V and 1.8 V voltages for the board are supplied from external power sources 
through connector J7. 

The current consumption of the MAYA-W1 module can be measured individually on each supply rail. 

3.3.1

 

Internal or external supply 

The EVB can be supplied through the host interfaces and voltages generated by internal DC-DC. To 
use internal supplies, place jumpers on pins 1-2 and 3-4 of pin header J7 (default configuration). 
To use external power sources, remove the jumpers and connect the supplies directly to the 

BRD_3V3, 

BRD_1V8

, and 

GND

 pins on J7.
