Flashing the Firmware

Once the hardware is wired up, you need to put the firmware onto the ESP32. There are two ways to do it:

• Web Flasher — flash straight from your browser, no tools to install. This is the easiest option for most people.

• Manual Build & Flash — build from source with the Rust ESP toolchain. Use this if you want to modify the firmware or build it yourself.

After flashing, continue with Configuration to pair the ATM with your LNbits wallet.
