Hello, I see the new ESP-WROOM-32D and ESP-WROOM-32U modules are available as:
ESP-WROOM-32D (4MB Default)
ESP-WROOM-32D (8MB)
ESP-WROOM-32D (16MB)
ESP-WROOM-32U (4MB Default)
ESP-WROOM-32U (8MB)
ESP-WROOM-32U (16MB)

Are the given MB values MBytes or MBits? I assume MBytes, which would mean the default modules have 4MBytes of flash = 32MBits. Can someone confirm this?

The IEEE convention is uppercase B for bytes, lower case b for bits, so 4MB = 4M bytes = 32M bits
