Rf Control And Coexistence Interfaces; Leds; Reset Button; Schematics - Ublox EVK-MAYA-W2 User Manual

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
R28
R29

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
Figure 13: Host interface configuration, RF control, and WCI-2 coexistence interfaces (J12)

3.10 LEDs

Table 11 describes the function and designation of the available LEDs on the EVK-MAYA-W2
evaluation board.

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.
