After programming is complete, disconnect GPIO9 from ground; otherwise, the module will not operate normally.<\/p>\n<p data-start=\"680\" data-end=\"699\"><strong data-start=\"680\" data-end=\"699\">Important Notes<\/strong><\/p>\n<ol data-start=\"701\" data-end=\"1510\">\n<li data-section-id=\"1kh1kz4\" data-start=\"701\" data-end=\"892\">The ESP8684 may draw an instantaneous RF current of up to 400\u2013500 mA. Therefore, the power supply must provide at least 500 mA. LDO regulators such as the XC6206 and 7533 must not be used.<\/li>\n<li data-section-id=\"1xen760\" data-start=\"894\" data-end=\"1129\">To meet the 500 mA power requirement, the power and ground traces should be at least 30 mil wide. If vias are required on the power traces, using two or three vias is recommended to reduce the impact of PCB manufacturing variations.<\/li>\n<li data-section-id=\"boh1rf\" data-start=\"1131\" data-end=\"1388\">For optimal RF performance, follow the module placement guidelines provided in the datasheet. If product certification is required, avoid routing parallel traces near the PCB antenna. The firmware download pads should be positioned away from the antenna.<\/li>\n<li data-section-id=\"c9cxax\" data-start=\"1390\" data-end=\"1510\">Completely erase the module\u2019s flash memory before downloading the firmware. Otherwise, some modules may fail to boot.<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>For bulk pricing or OEM\/ODM solutions, please contact\u00a0<a href=\"mailto:lihonggang@doit.am\">\u00a0<b>lihonggang@doit.am<\/b><\/a><\/p>\n","protected":false},"featured_media":188,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[15],"product_tag":[],"class_list":["post-243","product","type-product","status-publish","has-post-thumbnail","product_cat-uncategorized","first","instock","shipping-taxable","purchasable","product-type-variable","has-default-attributes"],"_links":{"self":[{"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/product\/243","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/comments?post=243"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/media\/188"}],"wp:attachment":[{"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/media?parent=243"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=243"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=243"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.doiting.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=243"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
