The board embeds the necessary electronics to power and control the avalanche photodiode, a high voltage transformer to provide the required 150 V for the piezo actuator; as well as a set of sensors (temperature, voltage, gyroscopes, etc.) to monitor the health of the payload. The whole system is manager by a 72 Mhz STM32 microcontroller.<\/p>\n<figure id=\"attachment_203\" aria-describedby=\"caption-attachment-203\" style=\"width: 429px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-203 \" src=\"\/picsat\/files\/2017\/01\/photo_carte-300x225.jpg\" width=\"429\" height=\"322\" srcset=\"\/picsat-news\/files\/2017\/01\/photo_carte-300x225.jpg 300w, \/picsat-news\/files\/2017\/01\/photo_carte-768x576.jpg 768w, \/picsat-news\/files\/2017\/01\/photo_carte-1024x768.jpg 1024w\" sizes=\"auto, (max-width: 429px) 100vw, 429px\" \/><figcaption id=\"caption-attachment-203\" class=\"wp-caption-text\">The payload electronic board.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>To control the piezo actuator which drives the optical fiber in the focal plane of the telescope, and to manage<\/p>\n<p class=\"readmore\"><a href=\"\/picsat-news\/payload\/payload-electronics\/\" title=\"Read Payload &#8211; Electronics\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":40,"featured_media":0,"parent":191,"menu_order":10,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-214","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"\/picsat-news\/wp-json\/wp\/v2\/pages\/214","targetHints":{"allow":["GET"]}}],"collection":[{"href":"\/picsat-news\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"\/picsat-news\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"\/picsat-news\/wp-json\/wp\/v2\/users\/40"}],"replies":[{"embeddable":true,"href":"\/picsat-news\/wp-json\/wp\/v2\/comments?post=214"}],"version-history":[{"count":2,"href":"\/picsat-news\/wp-json\/wp\/v2\/pages\/214\/revisions"}],"predecessor-version":[{"id":230,"href":"\/picsat-news\/wp-json\/wp\/v2\/pages\/214\/revisions\/230"}],"up":[{"embeddable":true,"href":"\/picsat-news\/wp-json\/wp\/v2\/pages\/191"}],"wp:attachment":[{"href":"\/picsat-news\/wp-json\/wp\/v2\/media?parent=214"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
