AVR Design Platform Hardware

Basic development modules and advanced features, to enhance the capability of AVR Design Platform beyond the design limitations. Its open structure and supported Learning Centre reduces the project design complexity for Engineers. All hardware sections are separately categorized with an open structure for the convenience of use and to deliver a clear knowledge of hardware sections.

Unique features of AVR Design Platform

Modular Structure for realizing hardware design

The modular structure of AVR Design Platform provides isolation between each development modules, sections and peripheral boards simplicity of design and easiness while learning and working on a modular platform. A beginner gets to know the exact circuit structure and the components involved in a particular project. This also enhances the effectiveness of learning.

Flexible port connection options of AVR Design Platform

Flexibility refers to a number of free-on-board connections available on AVR Design Platform. There are default ports on AVR Design Platform but the user can make use of the free ports instead of the default ports. That means there are no permanent connections between the controller and various ports.

Programmer/ Debugger mode to Running mode switching feature

The user-friendly design adds to the convenience of use of the AVR Design Platform. It is quite easy to switch between the running mode and programming mode with the help of toggle switches mounted on-board. The switching between programming mode and running mode has been made easy with the help of an in-circuit programmer. Besides, the AVR Design Platform is highly extendable which means the user can interface extra elements either using add-on boards or with the help of breadboard.

MEMORY DEVICE
