- PRODUCT DETAILS
Atom Lite, which has a size of
only 24*24mm, is a very compact development board 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 and Bluetooth 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.

USB Drive problems
UnitV/M5StickV/M5StickC/ATOM may not work without driver in some systems. Users can manually install
to fix this problem. Take the win10 environment as an example, download the driver file that matches the operating system, decompress it, and install it through the device manager. (Note: In some system environments, the driver needs to be installed twice for the driver to take effect. The unrecognized device name is usually
USB Serial. Windows recommends using the driver file to install directly in the device manager (custom Update), the executable file installation method may not work properly).

ATOM Lite ESP32 IoT Development Kit
I use it with a ENV-III sensor and sent my old setup (noname Esp32 with BME280 sensor) into retirement. Best thing is that everything comes in nice enclosures and has the same connectors.
Fine and fast esp32 iot modules - iot out of the box
The ATOM Lite ESP32 is great for any microcontroller project that requires only a handful of I/O ports (6, 8 if you include the grove port). With WiFI, IR, a built-in button and RGB LED, there's a lot packed into its package.
The USB C port is a nice upgrade relative to the old micro USB ports you still see on many microcontrollers.
The only drawback I've noticed for these devices is the somewhat weak wifi range. It's possible to open it up and solder an external antenna, which helps greatly, but definitely be ready to sacrifice a device or two-- it requires some soldering skills and a steady hand.
Overall a great device at a great price.
I used my ATOM Lite to emulate the keyboard for the Tektronix 4041 GPIB controller. I soldered a surface mount 3.3V to 5V level shifter inside the ATOM Hat PCB and used three breadboard jumper cables to connect to the 4041. The ATOM Lite sends commands to change the 4041 console to the RS-232 serial port, instead of requiring a file on a DC100 tape. Since the ESP32 has so much storage space, I also added a couple of BASIC programs that can be sent to the 4041 by pressing and holding the top button on the ATOM Lite longer. The ATOM Lite also has a battery option, but I didn't need it in my application - I use 5V from the 4041 keyboard connector to power the ATOM Lite.
