По файлам линковки 128KB Code (IRAM) and 512KB (DRAM) Data Memory линейные, не собраны из кусков, как у некоторых...
Но чип всё равно слабенький для поделок в 2019 году... На замену всех ESP пойдет. :)

сколько стоит доставка?
обычно это не менее 17$ в итоге 40 или 2800 руб
тогда дешевле взять здесь
