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 dual-
band 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.

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.
