The Unit Expansion Modules allow users to create their own uncomplicated designs and enhancements, while ensuring complete dimensional and connectivity compatibility with the original M5Stack Unit Series functional overlays. With the use of these small devices, users can independently design and run simple IoT systems, using both a variety of external devices (controlled, for example, via a relay) and simple electronic circuits, built from discrete THT components.

Unit expansion modules available at Botland store
In our offer all the time we invariably take care of the needs of all those who are not intimidated by building their own electronic circuits and experimenting with new technologies. That's why, among other things, we have introduced simple expansion modules to our regular offer, allowing you to extend the functions of M5Stack Unit series controllers with mechanical buttons, joysticks, potentiometers or limit switches.
We also have several models of prototype (universal) boards, allowing you to build electronic circuits consisting of a few...a dozen or so through-hole elements - thanks to them you will be able to build, for example, the necessary analog circuit, based on an operational amplifier or comparator, make an adapter for connection to another module, or bring out all four lines of the wired interface used in M5Stack modules and check the operation of the entire system, listening to the communication on the link of another Unit using any logic state analyzer.
In this category you will also find an audio/video module with composite ports, 8-channel sets of potentiometers and rotary encoders, or finally.... a miniature LED flashlight, based on a super-bright white LED. Also check out the other categories, which include Unit modules with sensors, displays and communication modules.
