1 Evaluation kit description
1.1 Overview
The EVK-ELLA-W1 evaluation kits provide a simple way to evaluate the ELLA-W1 host-based multiradio modules
with Wi-Fi and Bluetooth [2]. The EVK-ELLA-W1 evaluation board comes with on-board antennas for Wi-Fi and
Bluetooth. External antennas can optionally be connected through U.FL coaxial connectors. The evaluation kit
includes a standard full-size SDIO adapter board (compatible with host sockets designed for SD memory cards)
for host communication.
The main features of the EVK-ELLA-W1 evaluation kit are:
Available for single and dual antenna variants of the ELLA-W1 module
SDIO 2.0 device interface via SDIO adapter board for host communication
On-board dual-band 2.4/5 GHz and 2.4 GHz chip antennas for Wi-Fi and Bluetooth
U.FL coaxial connectors for external Wi-Fi and Bluetooth antennas, switchable by 0 Ω resistors
All module interfaces externally available
Multiple power supply options
Table 1 lists the different evaluation kit versions:

2 Getting started
This section describes the evaluation board connectors and configuration settings required to get started.
Figure 2: Evaluation board EVB-ELLA-W1 with default jumper settings
Figure 2 shows an overview of the evaluation board and its connectors. The EVK-ELLA-W161 shares the dualband antenna A1 for Wi-Fi and Bluetooth communication, while the EVK-ELLA-W163 uses the separate antenna
A2 for Bluetooth. With the default jumper settings, as shown in Figure 2, power supply from the SDIO interface
is used for power supply of the module and the board and I/O voltage is set to 3.3 V. Connect the included SDIO
adapter to connector J1 on the evaluation board via the ribbon cable as shown in Figure 1.
2.1 Connecting the evaluation board to the host
Connect the evaluation board to an SDIO capable host by inserting the adapter into the SD card slot. As the
ELLA-W1 series module uses an SDIO host interface, only an SDIO capable card reader (not just a common SD
card reader) will be able to transfer the data and interrupts correctly. You can use either a built in reader (usually
found in laptops – but not all models support SDIO), or a separate reader in one of the extension slots.
An example card reader for Linux is the “Sonnet SDXC UHS-I Pro Reader/Writer ExpressCard/34” [5].
Be careful while inserting the SDIO adapter of the EVK-ELLA-W1 into the SDIO slot of a laptop.
Such built-in readers might be designed poorly and can be damaged easily compared to the
ones found on development platforms, which are more compact.
The next step is to install the necessary driver software for the ELLA-W1 series modules as described in section 4
of this document.

settings.

3.2 Power supply
Different power supply options can be applied to the board using the dual-row pin header J5, which allows to
measure current and do performance tests under varying supply conditions. All the required voltages (3V3, 1V8
and VIO) can be supplied from the SDIO bus or from external power supplies. An on-board LDO can generate
1.8 V from a 3.3 V input. VIO voltage can be selected between 1.8 V and 3.3 V.
Table 4 lists the available power supply configuration options.
Be careful when configuring the power supply settings, as wrong configurations can cause
short circuits and damage the evaluation board and the host system.
