jczic/ESP32-MPY-Jama
v1.2 - UI tool for manage Espressif ESP32 microcontrollers with embedded MicroPython for MacOS, Windows and Linux: mini IDE, files manager, REPL, real time dashboards (sys/net), advanced features (gpio/mp3/leds/...)
ESP32-MPY-Jama is a desktop GUI (pywebview-based) for working with ESP32 boards running MicroPython: a lightweight code editor, REPL, file manager for the board's flash/SD card, real-time GPIO and network dashboards, and esptool-backed firmware flashing, all in one app. It's aimed at MicroPython/ESP32 hobbyists and embedded devs who are currently juggling Thonny, a serial terminal, and esptool CLI calls separately.
The feature set is genuinely consolidated rather than superficial — IDE, REPL with command history, file transfer, GPIO/network dashboards, and firmware flashing all live in one window instead of five separate tools. The 'Jama Funcs' concept is a practical pattern: small parameterized scripts (I2C scan, NeoPixel/DotStar control, MP3 module via UART, 1-Wire scan, servo PWM, etc.) that run on-device with GUI-configured params, plus a template so you can write your own. It ships built-in pinout diagrams for most common ESP32 dev boards and direct esptool integration, which removes real friction from the flash-then-test loop. Prebuilt signed-looking binaries are provided for macOS (universal2) and Windows so non-Python users can just run it.
The project is dead: last push was May 2023, so it predates three-plus years of Python, pywebview, and MicroPython changes that a GUI serial tool is exactly the kind of thing to break against silently. There are no tests and no CI configuration anywhere in the repo — for an app juggling serial I/O, threading, and OS-specific GUI backends across Mac/Windows/Linux, that's a lot of fragile surface with zero automated coverage. Linux support is explicitly second-class: no binary is offered, and setup requires hand-installing PyQt5/GTK/webkit system packages whose exact names drift between distro versions, which is the first thing likely to rot. It's a single-maintainer project with custom, non-reusable plumbing (its own microWebSrv.py, esp32Controller.py) rather than built on established serial or packaging libraries, so there's no obvious path for someone else to pick it up if jczic doesn't come back to it.
