On: Basic Interpreter Hidden in ESP32 Silicon

[tredre3]

The ESP32 has 448KB of ROM that embeds most of newlibc as well as wireless drivers and part of the bluetooth stack.

From past experience I can say that tinybasic can go down to about 3-4KB in size.

So it was probably "free" in that they had already decided on a rom size to embed and they had some space left.
