The MCP23017 digital port expander allows you to expand the number of system inputs\/outputs. Each expander can add an additional 16 ports to the system. The connection is made via the I2C bus using SDA and SCL control signals.You can connect up to 4 modules, thereby expanding the number of system ports to 64 digital inputs\/outputs.For proper operation of the system, you need to connect the SDA and SCL, they must be connected to the power supply on the module, if this is not the case, then pull them up \u2026 Read more<\/a><\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[74],"tags":[76],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/posts\/946"}],"collection":[{"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/comments?post=946"}],"version-history":[{"count":1,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/posts\/946\/revisions"}],"predecessor-version":[{"id":948,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/posts\/946\/revisions\/948"}],"wp:attachment":[{"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/media?parent=946"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/categories?post=946"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/iotmanager.org\/en\/wp-json\/wp\/v2\/tags?post=946"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
