EVK-IRIS-W106-RW612

Overview

The EVK-IRIS-W10x evaluation kit enables stand-alone use of the IRIS-W10 series module. This guide provides details about the hardware functionality of the EVK-IRIS-W10 board and includes setup instructions for starting development.

All pins and interfaces supported on IRIS-W10 series modules are easily accessible from the evaluation board. Simple USB connections serve as the physical interfaces for power, programming COM ports, debugging, and USB peripheral connectors. Additionally, the board features other interfaces like Ethernet RJ45 and an SDIO header. The EVK-IRIS-W10 board is equipped with a Reset button, Boot button, and two user-configurable buttons. Current sense resistors are incorporated for accurate current measurement within the module.

For flexible use, GPIO signals are accessible through headers and are complemented by four mikroBUS™ standard slots for convenient utilization of Click boards™. Each Click board can be seamlessly plugged into an available mikroBUS™ slot to facilitate effortless hardware expansion with a variety of standardized compact add-on boards. Click boards are designed to accommodate a diverse range of electronic modules, including sensors, transceivers, displays, encoders, motor drivers, connection ports, and more. For further information about the Click boards, visit the MIKROE website.

Connect a USB cable from your PC to USB3, and use the serial terminal of your choice (minicom, PuTTY, etc.) with the following settings:

Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1

Flashing

Here is an example for the hello_world application.

Open a serial terminal, reset the board (press the RESET button), and you should see the following message in the terminal:

**** Booting Zephyr OS build v4.1.0-2794-g6463c68bc394 ****
     Hello World ! ubx_evk_iris_w1/rw612

Wireless Connectivity Support

Fetch Binary Blobs

To support Bluetooth or Wi-Fi, ubx_evk_iris_w1 requires fetching binary blobs. This can be achieved by running the following command:

west blobs fetch hal_nxp

Bluetooth

BLE functionality requires fetching binary blobs, so make sure to follow the “Fetch Binary Blobs” section first.

The required binary blob <zephyr workspace>/modules/hal/nxp/zephyr/blobs/rw61x_sb_ble_a2.bin will be linked with the application image directly, forming a single monolithic image.

Wi-Fi

Wi-Fi functionality also requires fetching binary blobs, so make sure to follow the “Fetch Binary Blobs” section first.

The required binary blob <zephyr workspace>/modules/hal/nxp/zephyr/blobs/rw61x_sb_wifi_a2.bin will be linked with the application image directly, forming a single monolithic image.
