The IDE then reports:

Sketch uses 17,208 bytes (8%) of program storage space. Maximum is 196,608 bytes.

[SidLeung]

@bbaltz505 We only have 152 KB of Flash storage for the current setup. Can change that in future releases.

[bbaltz505]

Ok. i can update boards.txt. What is the exact # of bytes? 155,648?

[SidLeung]

Yes, it's 155,648 bytes.

[bbaltz505]

@SidLeung Corrected the max sketch size.
