2 Getting started
This chapter describes the basic settings and procedures to get started with EVK-JODY-W3.
☞
An overview of the EVB and its main connectors is shown in Figure 1. For more detailed
description of the available connectors and configuration options, see
Board description .
Follow the procedure below to evaluate JODY-W3 series module using EVK-JODY-W3:
1.
Connect the coaxial cables to the U.FL connectors on the module board and internal antennas on
the carrier board; or to SMA connectors for use with external antennas or conducted test setup.
The default antenna configuration is described below:
o
EVK-JODY-W374 uses both of its two internal dual-band antennas for Wi-Fi and Bluetooth
communication.
o
EVK-JODY-W377 uses one of its two internal antennas for Bluetooth, and Wi-Fi
communication is configured for use through SMA connectors SMA1 and SMA2. Connect
the two supplied external antennas to the selected SMA connectors on the EVB.
For more information about the antenna configuration, see also Antenna interfaces .
2. Set DIP switch SW503 to select the host interfaces for Wi-Fi and Bluetooth from the possible
combinations PCIE-UART, SDIO-UART or SDIO-SDIO, as described in
Bootstrapping .
3. Configure the power supply source as described in Power supply configuration and shown in
Table 5. The most common configuration uses the Wi-Fi host interface as the supply source,
which can be either PCIe or SDIO.
4. Connect the host interfaces to the host system. The EVB and supplied PCIe and SDIO adapters
use zero insertion force (ZIF) connectors with flat cables for connecting the adapters. To connect
the cable, gently flip up the small locking flap of the connector, align and insert the flat cable with
the blue marking pointing upwards, and then close the locking flap.
o
For PCIe connection to the host, use either the M.2 or the mini-PCIe adapter depending on
the available connector on the host platform. First, plug the adapter into the PCIe connector
on the host system. Then connect it with the flat cable to the connector (J203) on the EVB,
as shown in Figure 2. The PCIe interface can be used for Wi-Fi communication with the
JODY-W3 series module.
