Plug an ESP32-S3 into your phone with a USB-OTG cable and the phone becomes the Cardputer: the ESP32 runs the app, your phone is its screen, keyboard, GPS and flasher.
Droidputter rebuilds open-source Cardputer apps on demand. Pick an app from the catalog or paste any GitHub repository, choose the target (a bare ESP32-S3 with no display, or a Cardputer ADV), and the build runs in the cloud in a couple of minutes. Then flash it from the phone, no computer involved, and the app appears on your screen the moment the board reboots.
Features
• Live mirror of the ESP32's screen on the phone
• The Cardputer's full keyboard as a soft keyboard, plus any Bluetooth keyboard
• Your phone's GPS forwarded to the app as if a GPS module were attached
• In-app flasher with verification, no PC needed
• Prebuilt M5Burner firmware from LauncherHub, flash-only
• Optional community verdicts: which apps work on which boards
Requires a phone with USB host (OTG) support and an ESP32-S3 board: M5Stack Cardputer ADV, StickS3, or any ESP32-S3 devkit on its native USB port.
