The UART interface for Bluetooth can be accessed either directly through J305, or through the
USB type-C connector J205 via a USB-to-UART bridge. For further information about the
Bluetooth UART interface, see section 4.6.

Antenna interfaces
The evaluation board includes two dual-band 2.4/5 GHz chip antennas (Pulse Electronics W3006) for
Wi-Fi and Bluetooth communication. Three standard 50
Ω
female SMA connectors are included to
connect external antennas or measurement instruments. The antenna interfaces are selected by
connecting designated u.FL connectors on the EVK with coaxial RF cables.
The module board has three u.FL connectors which connect to the antenna pins of the JODY-W3
series module. To use any of the chip antennas or SMA connectors on the EVK, connect a coaxial RF
cable between the u.FL connector on the module board and u.FL connector on the carrier board, as
shown in Figure 20 and Figure 21.
Table 11 describes the available radio interfaces of the modules and the default antenna interfaces
which are selected on the EVK.
