Krabi\u010dka se naz\u00fdv\u00e1 Raspberry Pi3, vyvinut\u00e1 byla na universit\u011b v Anglii a je vyu\u017e\u00edvan\u00e1 v mnoha aplikac\u00edch.

Pokud chcete vid\u011bt schema cel\u00e9, je nutno si ho p\u0159ekop\u00edrovat, nebo\u0165 po posledn\u00ed aktualizaci WordPressu zmizela mo\u017enost obr\u00e1zek posouvat pomoc\u00ed posuvn\u00edku. Po zmen\u0161en\u00ed na \u0161\u00ed\u0159ku str\u00e1nky by zmizely detaily a schema by bylo ne\u010diteln\u00e9.<\/p>\n
