ESP32 MPY-Jama is a MicroPython IDE for ESP32 boards

ESP32 MPY-Jama is a cross-platform MicroPython IDE specifically designed for ESP32 boards with a file manager, a  REPL terminal, real-time dashboards, and various ESP32-specific features.

The IDE is an open-source Python program using pyWebView and pySerial plus some JavaScript for the user interface, and the developer of the program, Jean-Christophe Bos, provides binaries for Windows 64-bit and macOS 64-bit Arm or x86. It’s also possible to use it in Linux but needs to be built from source.

Some of the key features of the ESP32 MPY-Jama IDE include:

  • MicroPython code editor with syntax highlighting
  • REPL interface
  • Access to information dashboards with real-time data about WiFi and Bluetooth connections, system info with GPIO status, CPU frequency, memory and SPI flash details
  • Easy 2-click methods to connect to WiFi and create an access point
  • Graphical interface to install a new firmware through esptool
  • Ability to create, import, and run “Jama Funcs” mini-applications with customizable parameters such as BLE Scan, I2C slaves scan, or Magnet sensor.

You’ll find the source code, links to Windows and MacOS binaries, a few screenshots, and instructions to build it in Linux on GitHub.

Jean-Christophe tested it in Ubuntu 22.04, but I tried install it in Ubuntu 20.04 with similar instructions (I had to add python3.10-venv to the dependencies):

But the terminal looked stuck while building wheel (which can apparently take a while), but after several minutes my laptop completly hung. My laptop is somewhat unstable under load or when messing around with HDMI/graphics. I tried again during lunch and the same problem occurred. So I switched to a mini PC running Ubuntu 22.04 and I had it up and running within 5 minutes:

Note “(venv)” above. If it is already installed on your system, but not in the Python virtual environment, the program will not find esptool. All in all, it looks like a pretty nice IDE for people working with ESP32 and MicroPython.
