Atom Lite, which has a size of only 24*24mm, is a very compact iot development kit in the M5Stack development kit series. It provides more GPIOs for user customization which is very suitable for embedded smart home devices and in making smart toys. The main control adopts the ESP32-PICO chip which comes integrated with Wi-Fi technologies and has a 4MB of integrated SPI flash memory. Atom Lite board provides an Infra-Red LED, a RGB LED, buttons, and a HY2.0 interface. In addition, it can connect to external sensors and actuators through 6 GPIOs. The on-board Type-C USB interface enables rapid program upload and execution.

    Great little gizmo

    Great little ESP module.
    Well built with very good interface for modules.
    I use it with the ModBus extension board, running my ventilation system in Home Assistant.
    Works great with ESP Home.

    great hardware, terrible documentation

    I have bought plenty of atom lites by now and not a single one has died or broke or anything. they just work.

    But try getting to work any sensor from m5stack with the atom or stamp and you will have a terrible time figuring it out by yourself.
    I do not only mean the hardly useable code examples on github which mostly only apply to the atom matrix but also the shop page is way below acceptable.

    let's give an example: buy any of the microphones and an atom lite and one other sensors. you will need quite some time to figure out that only the pdm microphone will work with other sensors on the hub and the unit mic will crash everything. you will spend time on researching for just one working code snippet to use the pdm mic on the atom. both the github and the shop are not on the level they need to be.

    Great hardware package but no debug capability

    It's a great platform to work on, it's small, has its own case, USB-C, and looks great! The common software debugger tools are not available for it, but other than that it delivers what I needed - An ESP32 in a box.
