This particular board has 8MB flash with no PSRAM. If the property is set to 4MB as in the current release version, platformio will throw an error while trying to flash any firmware to the board.

Setting flash_size to 8MB fixes the issue.

There are two boards variants availabe sold with the same name.

So it needs a more precise definition in the name
Anyway this definition is wrong, and 8MB is correct for the board without PSRAM.
