Hierbei sind die ESP32-Platinen beim schnellen Ali aufgefallen. Diese kommen komplett verwendbar daher und haben zum Teil sogar eine 240V-Stromversorgung mit on Board.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ACHTUNG: Der Programmierport auf den Boards ist zwar mit 5V ausgewiesen, der Umstand, dass meine Platinen aber nur einmal programmierbar waren, l\u00e4sst mich darauf schlie\u00dfen, dass die 5V nur die Versorgungsspannung sind und die Datenleitungen nur mit 3V arbeiten. Zum Gl\u00fcck hatte ich beim ersten Versuch OTA aufgespielt. Ich werde dennoch mal schauen, ob ich den ESP auf einem Board ersetze.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fakten\"><span class=\"ez-toc-section\" id=\"Fakten\"><\/span>Facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table id=\"wpls-table-1\"><tbody><tr><td><strong>Description<\/strong><\/td><td>Board 1 Relay Programmer<\/td><td>1 Relay + Power Supply<\/td><td>4 Relays + Power Supply<\/td><\/tr><tr><td>Versorgungsspannung DC<\/td><td>5V-60V<\/td><td><\/td><td>5V-30V<\/td><\/tr><tr><td>Versorgungsspannung AC<\/td><td>\u2013<\/td><td>90V-250V<\/td><td>240V<\/td><\/tr><tr><td>Controller<\/td><td>ESP32-Wroom-32E<\/td><td>ESP32-Wroom-32E<\/td><td>ESP32-Wroom-32E<\/td><\/tr><tr><td>Switch<\/td><td>1<\/td><td>1<\/td><td>4<\/td><\/tr><tr><td>Relay coil voltage<\/td><td>5V<\/td><td>5V<\/td><td>5V<\/td><\/tr><tr><td>Relais Kontakt Spannung Max<\/td><td>30V DC<br>250V ac<\/td><td>30V DC<br>250V ac<\/td><td>30V DC<br>250V ac<\/td><\/tr><tr><td>Maximum relay current<\/td><td>10A<\/td><td>10A<\/td><td>10A<\/td><\/tr><tr><td>Relay Contacts<\/td><td>NC\/COM\/NO*<\/td><td>NC\/COM\/NO*<\/td><td>NC\/COM\/NO*<\/td><\/tr><tr><td>USB Port<\/td><td>Micro USB<\/td><td>\u2013<\/td><td>\u2013<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><td><\/td><\/tr><tr><td>Size<\/td><td>57.5mm x 53.7mm<\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Boardeigenschaften <br>Normal Closed\/ Supply Voltage\/ Normal Open<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table id=\"wpls-table-2\"><tbody><tr><td><strong>Description<\/strong><\/td><td><strong>1 Rel.

Zwei der drei Boards haben keinen Programmieradapter on board, das ist zwar leicht durch einen externen Programmierer behebbar, aber dennoch eine Last. Die Boards sind sehr speziell, aber wer ein Board mit einer Netzspannungsversorgung sucht und ein paar Dinge schalten m\u00f6chte, hat zumindest mit den zwei Boards mit Spannungswandler ein Komplettpaket. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"verwandte-beitraege\"><span class=\"ez-toc-section\" id=\"Verwandte_Beitrage\"><\/span>Related Posts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<ul class=\"display-posts-listing\"><li class=\"listing-item\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a class=\"title ub-content-link__anchor\" href=\"https:\/\/www.fambach.net\/en\/esp01-relay-platinen\/\">ESP01 Relay Boards<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/li><li class=\"listing-item\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a class=\"title ub-content-link__anchor\" href=\"https:\/\/www.fambach.net\/en\/esp32-relay-platine\/\">ESP32 Relay Board<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/li><li class=\"listing-item\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a class=\"title ub-content-link__anchor\" href=\"https:\/\/www.fambach.net\/en\/preview-esp01-relais-modul\/\">ESP01 \u2013 Relais Platine<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/li><li class=\"listing-item\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a class=\"title ub-content-link__anchor\" href=\"https:\/\/www.fambach.net\/en\/hjr-4102-l-5v\/\">Arduino 4-Relay Expansion Board<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"quellen\"><span class=\"ez-toc-section\" id=\"Quellen\"><\/span>Sources<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a href=\"https:\/\/de.aliexpress.com\/store\/912246115?spm=a2g0o.detail.0.0.76fa7c1fXWn9rP\" class=\"ub-content-link__anchor\">https:\/\/de.aliexpress.com\/store\/912246115?spm=a2g0o.detail.0.0.76fa7c1fXWn9rP<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>F\u00fcr ein anderes Projekt brauchte ich Relais, um ein paar Pumpen schalten zu k\u00f6nnen.
