Dear All,
I would like to test the ESP32 firebeetle to check the power consumption in deep sleep mode.

I'm compiling a sketch that works on another board from another manufacturer (so not a Firebeetle V4).
I updated the "preferences" with: "https://git.oschina.net/dfrobot/FireBeetle-ESP32/raw/master/package_esp32_index.json"

In the "board manager" choice menu, I selected "FireBeele-ESP32" and the USB port.

The compilation goes well but when I try to upload the board I get the following message:

Sketch uses 1006225 bytes (76%) of program storage space. Maximum is 1310720 bytes.
Global variables use 40440 bytes (12%) of dynamic memory, leaving 287240 bytes for local variables. Maximum is 327680 bytes.

Do you have any idea what I should do ?
