J2B: Universal MMI Module using ARM Cortex-M3

Let’s stop reinventing the wheel!

J2B: Universal MMI Module using ARM Cortex-M3
When we take a closer look at circuits using a microcontroller, it can be seen that in 75 % of cases the basic circuit is virtually identical: a microcontroller, an LCD display, and a few push-buttons. This observation is nothing new, and Elektor in particular has already suggested several solutions. This article presents yet another way of going about it, a little bit more universal, which allows the use of several types of LCD and a variable number of buttons. And thanks to its up-to-the-minute LPC1343 ARM Cortex-M3 processor, this board is extra powerful and amazingly easy to use.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor 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.
