What are mexdulon tetra-Boards?
mexdulon tetra-Boards are a modular system for experimenting with digital electronics. The set consists of different boards that are connected via cables. Thus, individual circuits can be created. Examples include a countdown on a segment display, a mini-keyboard, a traffic signal, an animation on a dot matrix display or a complete computer unit. The modular design allows almost unlimited possibilities.
mexdulon tetra-Boards are suitable for beginners and don't require special knowledge. The wiring of the connectors is non-polar and thus preventing shorts. The power supply is realized via a mini-USB socket on one board to comply with the required 5V. All connected boards can be supplied via a power bank (portable battery), so no special power supply (not even a socket) is required.
The boards are independent of computers, software or microcontrollers. There is no programming and no additional equipment required. They are just pure hardware modules with self-sufficient function. However, if you want to use an Arduino you can combine it via the Arduino Shield with tetra-Boards. That allows you to program your own application.
Modular Building Blocks
The system consists of many different boards, which can be arbitrarily combined with each other. There are modules for the input and output, logical operations, storage, etc. Example modules are buttons, gates, counter, display and multiplexer.
mexdulon tetra-Boards are published as open source hardware in our GitHub. All schematics, layouts and documentation files of the boards are released under a copyleft license. Thus, you can improve any existing boards or develop your own compatible modules.
