Как можно съесть слона? По кусочку за раз
Один из моих подопытных - отладочная плата Open407I-C
Покупал всё там же - на Ebay. Примерно с год назад, когда на работе начали новый проект с использованием STM32F2xx. Мы делали промышленный контроллер, сроки были сжатыми и нужно было быстро-быстро определиться с производительностью этого контроллера.

Что есть на плате
0 MCU core board connector: for easily connecting the Core407I

02.06.2013 в 21:56вон, по ссылке выше есть цена
или вот
есть, кстати, почти такая же мат.плата, но вместо Core407 там DiscoveryF4 устанавливается - вот
очень удобный конструктор =)

03.06.2013 в 10:45я одно время, глядя на него, всерьёз думал развести себе платку расширения для дискавери (на семинаре раздавали) - только чтоб прицепить LCDшник )))
