With a patch queued into hwmon-next, those voltage measurements are being propagated to the Linux user-space via the conventional HWMON sysfs interfaces.\n<\/p>\n<p>This includes in0_input for the core voltage, in1_input as the SDRAM controller voltage, in2_input as the SDRAM I\/O voltage, and in3_input as the SDRAM PHY voltage. All measurements are in millivolts.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=raspberry-pi-5-16gb&#038;image=raspberrypi5_16gb_2_med\" alt=\"Raspberry Pi 5\"\/><\/p>\n<p>With this patch making it into the hardware monitoring subsystem&#8217;s hwmon-next Git branch, it should be submitted as part of the changes for the Linux 7.2 merge window in mid-June.<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/Raspberry-Pi-Voltage-Inputs\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Linux Driver To Expose Voltage Inputs For Raspberry Pi SBCs https:\/\/www.phoronix.com\/news\/Raspberry-Pi-Voltage-Inputs Publish Date: 2026-05-27 06:15:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":256665,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=raspberry-pi-5-16gb&image=raspberrypi5_16gb_2","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-256664","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256664"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=256664"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256664\/revisions"}],"predecessor-version":[{"id":256667,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256664\/revisions\/256667"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/256665"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=256664"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=256664"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=256664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
