Editor and run
Highlighting and line numbers. “Run” executes on the board, “upload as main.py” makes it start on power-up.

without the command line
Editor, board console, firmware and RobX cloud in one window. Plug the ESP32 in over USB, press “Run” — the program is running.

Setup takes a minute. Updates arrive on their own.
One window: code, board files and console. Nothing else to install.
Everything a lesson needs
Four things that usually take three separate programs and a terminal window.
Console and board files
A live REPL and the ESP32 file tree: open, edit, upload, delete.
RobX cloud storage
Your cloud files right inside the program. Saved in class — opened at home, no flash drives.
Firmware and libraries
Flash MicroPython and install libraries from the window — no esptool, no command line.
Three steps to the first program
1
Download and install
The button above. An installer on Windows, a .dmg image on macOS, an archive on Linux.
2
Plug the board in over USB
Studio finds the port itself and marks the board with a star. CH340 and CP210x may need a driver.
3
Write it and run it
Code in the editor, press “Run” — output in the console. Happy with it? “Upload as main.py”, and it runs without a computer.
Studio recognises the board Studio reads the identifier the board reports to the system when plugged in and marks it with a star in the port list. Board not listed? The port can always be picked by hand.
Works with any ESP32 board. The only difference is whether it needs a USB–UART bridge.
| Board | How it connects to the computer | USB–UART bridge A chip on the board that makes the computer see it as a serial port. ESP32-S2, S3 and some C3 boards do not need one: the controller talks USB itself. | VID:PID identifier |
|---|---|---|---|
| ESP32 (classic) | Through an external USB–UART bridge on the board | CP2102, CP2102N, CH340, CH9102, FT232, FT2232 | 10C4:EA60, 1A86:7523, 0403:6001 |
| ESP32-S2 | Native USB (CDC), no bridge needed | — | 303A:* |
| ESP32-S3 | Native USB (CDC), no bridge needed | — | 303A:* |
| ESP32-C3 | Native USB (CDC) or an external bridge — depends on the board | The same bridges when there is no native USB | 303A:* or the bridge ID |
What people ask on day one
Do I need Python on the computer?
No. The program runs on the board itself, and Studio already contains everything needed to talk to it.
The board is not in the port list
Usually a missing CH340 or CP210x bridge driver. Install the driver, replug the cable and press “Refresh” in the port list. If the board is still missing, the port can be picked by hand.
The board has no MicroPython — what now?
Flash it from the same window: Studio downloads the firmware for your chip and writes it. No command line, no esptool.
Can it work offline?
Yes. The internet is only needed for cloud storage, installing libraries and program updates.
Is Studio really free for a school?
Yes, with no limit on computers or classes. No licence required.
Set up a whole class in one lesson
One installer, no environment setup and no command line. After that: a board, a cable and the first program.
