AVR-IoT Wx Hardware User Guide
Preface
Important:
This document is applicable for two different products; AVR-IoT WG (AC164160) and AVR-
IoT WA (EV15R70A). Both variants are referred to as AVR-IoT Wx in this document, and both products
have identical hardware. AVR-IoT WG is preconfigured to send data through Google Cloud IoT Core, and
AVR-IoT WA is preconfigured to send data through Amazon Web Services (AWS). Both products can be
reconfigured to send data to different cloud providers.
Introduction
The AVR-IoT Wx Development Board is a small and easily expandable demonstration and development platform for
IoT solutions, based on the AVR
®
microcontroller architecture using Wi-Fi
®
technology. It is designed to demonstrate
that the design of a typical IoT application can be simplified by partitioning the problem into three blocks:
microcontroller
• Secure - represented by the
secure element
• Connected - represented by the
The AVR-IoT Wx Development Board features the following elements:
• The on-board debugger (PKOB nano) supplies full programming and debugging support through Atmel Studio/
MPLAB X IDE. It also provides access to a serial port interface (serial to USB bridge) and two logic analyzer
channels (debug GPIO).
• The on-board debugger enumerates on the PC as a mass storage interface device for easy ‘drag and drop’
programming, Wi-Fi configuration, and full access to the microcontroller application Command Line Interface
(CLI)
• A mikroBUS

socket allows for the ability to expand the board capabilities with the selection from 450+ sensors
and actuators options offered by MikroElektronika (
