ATOM Matrix ESP32

by M5Stack

Image of Board

ATOM Matrix, which has a size of only 24 * 24mm, is the most compact development board in the M5Stack development kit series. It provides more GPIO pins and is very suitable for handy and miniature embedded device development. The main control adopts the ESP32-PICO-D4 chip, which comes integrated with Wi-Fi technologies and has 4MB of integrated SPI flash memory. The Atom board provides an Infra-Red LED along with the 5 * 5 RGB LED matrix on the panel, a built-in IMU sensor (MPU6886), and a HY2.0 interface. A general purpose programmable button is proved below the RGB Led matrix to enable users to add input support to their various projects. The on-board USB interface (Type-C) enables rapid program uploading and execution. One M2 screw hole is provided on the back for mounting the board.

Features

  • ESP32 PICO-based
  • Programmable button
  • 5 * 5 RGB LED matrix panel(WS2812C)
  • Built-in Infra-red LED
  • Built-in MPU6886 Inertial Sensor
  • Extendable Pins & Holes

CircuitPython 9.1.0-beta.0

This is the latest development release of CircuitPython that will work with the ATOM Matrix ESP32.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
