The first one is for the general operation of the board and the ESP32-S3, PSRAM and Flash.\u003c\/p\u003e\n\u003cp class=\"text mb-2\"\u003eThe second LDO is for you to use to connect external 3V3 modules, sensors and peripherals, and it has programmable EN control tied to IO39 + it’s connected to the deep sleep capabilities of the ESP32-S3, so if the ESP32-S3 goes into deep sleep, the 2nd LDO is automatically shut down for you! LDO2 also powers the onboard RGB LED.\u003c\/p\u003e\n\u003cp class=\"text mb-2\"\u003eBoth regulators are ultra low noise and have ultra low quiescent current, and both support a maximum of 700mA output.\u003c\/p\u003e\n\u003ch3\u003e2x STEMMA QT connectors?\u003c\/h3\u003e\n\u003cp class=\"text mb-2 mt-2\"\u003eYes! Each STEMMA\/QT connector has unique IO, allowing you to instantiate two different I2C buses, or use the one labelled I2C1 for I2C (as that is already connected to the I2C fuel gauge) and use the one labelled I2C2 as an easy-to-connect UART or something else.\u003c\/p\u003e\n\u003cp class=\"text mb-2 mt-2\"\u003eI2C1 is powered from the main LDO, which means it will stay powered up even when the ESP32-S3 chip is put into deep sleep. I2C2 is powered from LDO2, which will automatically shut down if the ESP32-S3 chip is put into deep sleep, so you get the best of both worlds as options for connecting your external peripherals.\u003c\/p\u003e\n\u003ch2 class=\"text mb-2 mt-2\"\u003ePinout\u003c\/h2\u003e\n\u003cp class=\"text mb-2 mt-2\"\u003e\u003cimg alt=\"Shape\" src=\"https:\/\/esp32s3.com\/images\/series_d\/pins_feathers3d.jpg\"\u003e\u003c\/p\u003e\n\u003ch2\u003ePlatforms\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/d2j6dbq0eux0bg.cloudfront.net\/images\/wysiwyg\/product\/90477757\/577111310\/1735085821321-319379275\/logo_dev_platforms_png.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eUnexpected Maker ESP32-S3 boards ship with CircuitPython pre-installed!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePlease check out the new PLATFORMS area of the \u003c\/span\u003e\u003ca href=\"https:\/\/esp32s3.com\/getting-started.html\"\u003eGetting Started\u003c\/a\u003e\u003cspan\u003e guide to find out all about developing for your new board in a range of different languages.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eResources\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eCheck out the \u003ca href=\"https:\/\/esp32s3.com\/feathers3d.html\" rel=\"noopener\" target=\"_blank\"\u003eFeatherS3[D] page\u003c\/a\u003e for schematics, dimensions, 3D models and more!\u003c\/span\u003e\u003c\/p\u003e","brand":"Unexpected Maker","offers":[{"title":"Default Title","offer_id":39762596298835,"sku":"FS3D-01","price":19.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/FeatherS3_D__Product.jpg?v=1753284149","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/feathers3-esp32-s3","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
