Modular-Electronics-Toolkit

This project is a diploma thesis done at the HTL Rankweil. It aims to provide future students with a better way to understand and work with different sensors and actuators. The system created aims to be modular so that different parts of it can be mixed to create new and creative projects. Different libraries are also provided to help students use these modules.

To further help with the development of different projects, a visual coding engine can be used to create the needed code. This is done with Blockly, which was developed by Google.

Key Features

Compability

The modules created should be compatible with any microcontroller, as long as they can handle 5 volts.

[!WARNING] The provided code and libraries have only been tested with a board using the ATMEGA16A-Chip. For other microcontrollers, you may need to create your own code.

Modular

The modules are designed to be able to create new projects by combining them together. As such, even complex problems can be solved easily.

Easy to use

The libraries are designed to be used by students and as such are easy to use and adapt to your project or solution. This is reinforced by the block-based code editor for easy project creation.

Questions

How big is the LED AL5887 PCB?

It measures 35 × 35 mm and has 2 copper layers, 1.6 mm thick.

What parts does the LED AL5887 use?

49 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the LED AL5887 KiCad files?

From the FluYVy/Modular-Electronics-Toolkit repository on GitHub, at the commit this page was made from: the board is Hardware/Modules/Pixel_Matrix/LED-AL5887.kicad_pcb and its schematic Hardware/Modules/7-Segment_Anzeige/7-Segment_MAX7221CNG_.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LED AL5887 design in my own project?

Its repository states no licence, so its author keeps all rights: ask FluYVy before reusing the design.
