Description

Atom Printer is a DIY thermal printer kit, featuring the Atom-Lite IoT core controller paired with a 58mm thermal printer. It supports printing characters, graphics, barcodes, 1D codes, QR codes, and more. The body is covered with a full cardboard shell, giving it a distinctive maker style. The built-in firmware supports two modes: AP connection printing and MQTT message push printing. Based on the ATOM IoT control core, you can further develop more cool printing applications.

Note: This kit does not come with a power adapter. Users need to prepare their own DC-12V (5.5mm specification) power adapter. For optimal print quality, the adapter should have a power supply capacity of 2.5A or higher, as the power supply capability will directly affect the print display quality.

Features

  • Atom-Lite: ESP32-PICO-D4 4MB Flash IoT controller
  • Geek-style cardboard shell
  • Supports printing characters, graphics, barcodes, QR codes
  • Communication interface: UART

Learn

After powering the ATOM Printer, the indicator light on the ATOM controller will show the current status and mode of the device. Click the middle button on the ATOM to switch between different modes (AP/MQTT).

Firmware Flashing

Click here to go to the download page and download M5Burner , and flash the printer program to the M5Atom. Before flashing, click Erase to clear, then click Burn to start flashing.

AP Mode

Indicator light:

    1. When no device is connected, the indicator light will blink green rapidly.
    1. When a device is connected, the indicator light will stay green.

Operation instructions:

    1. When switching to AP mode, the device will start an AP hotspot ATOM_PRINTER_, which users can connect to directly using a phone or computer (no password required).
    1. After successful connection, the connected device will automatically pop up a configuration page. On this page, you can directly input content for printing text, QR codes, and 1D codes.
    1. At the bottom of the page is the WiFi configuration option, which allows you to configure the device to connect to a specified WiFi and switch to MQTT mode.

MQTT Mode

Indicator light:

    1. When WiFi connection fails, the indicator light will blink red rapidly.
    1. When WiFi & MQTT server are not yet connected, the indicator light will blink blue rapidly.
    1. When WiFi & MQTT server are successfully connected, the indicator light will stay blue.

Operation instructions:

    1. Before switching to MQTT mode, you need to configure the WiFi information through the AP mode configuration page. After completing the configuration, the device will automatically restart and enter MQTT mode.
    1. If WiFi connection fails multiple times, you can press the middle button on the ATOM to switch back to AP mode and reconfigure the WiFi information.
    1. After successfully connecting to the MQTT server, the ATOM Printer will automatically print the subscribed Topic information (Topic is the device's Mac address).
    1. Users can connect to mqtt.m5stack.com (port 1883) via UIFlow or other tools (such as EMQ MQTT Tools ) and send content to the corresponding ATOM Printer device's Topic to achieve remote printing.
