C1 – Public
The antenna interface of EVK-MAYA-W276 can be changed to SMA connector J11 by removing 0
Ω
resistor R29 and populating R28 instead, as shown in Figure 12 .

3.9 RF control and coexistence interfaces
Figure 13 shows the module RF control signals and the WCI-2 coexistence interface accessible on pin
header J12. The external PTA coexistence interface of MAYA-W2 is shared with the SPI pins on J13
as described in
Table 7 .

3.11 Reset button
Press the SW1 button on the EVB to reset the MAYA-W2 module. When pressed, SW1 asserts the
PDn
pin of the MAYA-W2 module to enter power down mode, while keeping the supply rails enabled.
The module is automatically reset when it exits the power down mode, which means that the firmware
must be downloaded again.
3.12 Schematics
Complete schematics for the MAYA-W2 evaluation board are available on request. For further
