Product description: M5Atom Matrix - RGB LED development module - ESP32.
The modules of theAtomseries are the smallest main modules created by M5Stack. The idea behind the development of the Atom series was to create a miniature master module with great possibilities. Another feature of theM5Stackdevices is thebanalway of combining accessories with master modules. Atom Matrix featuresa 5 x 5 RGB LED matrixon the front of the device. The Atom Matrix is a perfect master module for all alarm and signaling systems based on light signals.

How to start working with the M5Atom Matrix
In order to work with the module you need a USB cable, with which we will program our module. This cable can also be used to power the module, an alternative to the wired power supply of the device is theATOM TailBatextensions, which acts as a powerbank. For proper operation of the device with a computer you will need a suitable driver - its installation has beendescribed in detailby the manufacturer.The manufacturer has also made specialEasy LoaderandM5Burnerapplications available. They enable easy installation of the required software for our small module.
Purpose of the M5Atom Matrix
The Matrix version is ideal for use wherever light signals are used, the Matrix can be successfully used as the main module to control the operation of sensors and signal when a phenomenon occurs. In this case you can use dedicated expansion modules fromM5Stackor sensors equipped with a connector known fromGrovesystem. Connection of the expansion devices is trivially simple and requires connecting the cable to theGroveconnector or to theGPIOconnector on the back of the device.
