I thus had to work with what was available, as well as take into consideration what will work with the standard factory firmware as well. <\/p>\n\n\n\n<p>The prototype carrier PCB will thus only have two optically isolated relays and their supporting circuitry. I intend to actually use the PCB in my EE LAb area to control some of the lights in the area.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"768\" height=\"1024\" data-src=\"http:\/\/makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-768x1024.jpg\" alt=\"\" class=\"wp-image-17860 lazyload\" data-srcset=\"https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-768x1024.jpg 768w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-225x300.jpg 225w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-1152x1536.jpg 1152w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-1536x2048.jpg 1536w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-1200x1600.jpg 1200w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/voicekit-carrier-scaled.jpg 1920w\" data-sizes=\"(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 768px; --smush-placeholder-aspect-ratio: 768\/1024;\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">The Schematic<\/h3>\n\n\n\n<p>The schematic shows the relay control circuitry, comprising of my standard optic isolator-based relay driver, as well as headers to accept the VC-01 or VC-02 offline voice module kit PCB. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"720\" data-src=\"http:\/\/makeriot2020.com\/wp-content\/uploads\/2022\/07\/Schematic_Offline-Voice-Module_2022-07-271-1024x720.png\" alt=\"\" class=\"wp-image-17902 lazyload\" data-srcset=\"https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/Schematic_Offline-Voice-Module_2022-07-271-1024x720.png 1024w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/Schematic_Offline-Voice-Module_2022-07-271-300x211.png 300w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/Schematic_Offline-Voice-Module_2022-07-271-768x540.png 768w, https:\/\/www.makeriot2020.com\/wp-content\/uploads\/2022\/07\/Schematic_Offline-Voice-Module_2022-07-271.png 1178w\" data-sizes=\"(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/720;\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Testing the PCB<\/h3>\n\n\n\n<p>The PCB was tested using the standard factory firmware, as well as my custom firmware, kindly provided by AI-Thinker.
