ESP Flasher writes firmware files to supported ESP boards over USB and provides a serial monitor. Select a valid firmware file, specify its flash address and connection settings, and follow operation progress.

A USB Host-capable phone, a compatible OTG adapter and a data cable are required. Your board may need to be placed in download mode manually. Connection guidance and settings are available in the app.


Persian and English interfaces are supported. Compatibility with every board or USB adapter is not guaranteed. An incorrect firmware file or flash address can damage the board firmware; check the board manufacturer's instructions before starting.
