My First Shield :-)

LEDs, buttons and more

My First Shield :-)
In the microcontroller world as elsewhere, learning by doing is a good approach. The Arduino Uno, which features especially low cost and a low entry threshold, has a significant shortcoming: almost no on-board peripherals. We have therefore developed a compact shield that gives starters a text display, LEDs and pushbuttons to provide a good basis for their first projects.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.

Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
