Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
The miniature M5Atom module is equipped with GPIO connectors and a Grove connector enabling the connection of additional sensors and extensions.
Accessories needed to work with the module
To run the M5Atom module, you'll need power. In this case, you can use a cable with a USB-C connector on one end or an ATOM series extension that acts as a power bank. A USB cable will also be necessary to upload your program to the device's memory. Installing the necessary drivers is also required; this process is thoroughly explained by the manufacturer . Additionally, M5Stack offers Easy Loader and M5Burner , which allow for easy installation of new software for our modules.
M5Atom Voice Applications
The M5Atom Voice main module can be used as a Bluetooth speaker , but that's just the beginning of its capabilities. The device can be programmed to use cloud platforms, and the built-in speaker and microphone make it suitable for voice-controlled systems. You can also connect any additional ATOM series devices to the module. Additional modules can be connected using the Grove interface. The module also has sockets for connecting goldpin jumper cables , but they do not support I2C or UART interfaces.
The M5Atom series are the smallest devices offered by M5Stack.
The M5Atom Voice is equipped with a speaker, a microphone, as well as a programmable button and LEDs indicating the device status.

Question: Good day I would like to use it for voice control in home assistant. In this regard, I have a question, how much microphone sensitivity does it have. Is one per room enough?
No direct manufacturers data is given specifying the range in meters, but microphones of this type typically operate effectively in the 3-5 meter range in a home environment with little background noise. For voice control with Home Assistant, for example, one microphone should be sufficient in an average room of 15-20 m², provided the noise level is moderate. If the room is larger or noisier, consider using more microphones for better range and accuracy. It will also be best to place the module centrally in the room, which can improve performance.
