Place jumpers J401 and J402 to enable the audio codec, as shown in Figure 16.
Figure 16: Jumpers to enable the audio codec
The I2C interface of the audio codec is provided on connector J303 of the EVB as shown in Table 10
and Figure 20. The PCM/I2S interface of the JODY-W3 module is directly connected to the serial audio
interface of the MAX9860 audio codec. The PCM pins are shared with the I2S interface and are
additionally provided on connector J301 as shown in Table 10 and Figure 19.

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 U.FL connectors on the EVB module board with designated U.FL connectors on the EVB
carrier board 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 EVB carrier board,
connect the coaxial RF cables between the U.FL connector on the module board and U.FL
connectors on the carrier board. See also
