Es besitzt einen ESP32-C3 und ist in einem Formfaktor, der auf ein Breadboard passt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What is a preview<\/strong>: Da ich immer mehr den \u00dcberblick \u00fcber die bestellte Hardware verliere, werde ich nach der Bestellung eine kleine Vorschau schreiben. Wenn ich dann zu der Hardware komme, werde ich das entsprechende Preview durch den eigentlichen Beitrag ersetzen. Somit erhaltet ihr die M\u00f6glichkeit, schon mal die bald kommende Hardware zu besichtigen und zu kommentieren. Die Beitr\u00e4ge werde ich dann nach euren Kommentaren oder nach meiner Laune und Zeit priorisieren ;). <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ansicht\"><span class=\"ez-toc-section\"
