Normally you have a switching power supply that plugs into the wall and provides something like 5V or 9V or 12V regulated DC.

The 'ring' of the white-cable connector is -12VDC. You can draw about 500mA from each side, a total of 1A. Please note that the output is not as strictly regulated as some other power adapters you may have used, the floating voltage can be +-13V and at max draw, droop down to +-11V or so. You may want to have an extra linear regulator if you want the output to stay rock-solid over a wide current-draw range.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eCable lengths: 1.2m each\u003c\/li\u003e\n\u003cli\u003e5.5mm \/ 2.1mm DC jack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 86.0mm x 48.0mm x 31.0mm \/ 3.4\" x 1.9\" x 1.2\" \u003c\/p\u003e\n\u003cp\u003eProduct Weight: 127.0g \/ 4.5oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48623658827994,"sku":"lfy1789674875599","price":14.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/switching-split-power-supply-12v-500ma-split-supply-discontinued_1.jpg?v=1789674881"},{"product_id":"lm3671-33v-buck-converter-breakout-33v-output-600ma-max","title":"LM3671 3.3V Buck Converter Breakout - 3.3V Output 600mA Max","description":"\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThis 3.3V buck converter breakout delivers up to 600mA from a 3.5–5.5V input (Li-Ion or USB) at 90–95% efficiency.

Voltages between 4.5 V and 38 V can be applied to VIN, but for versions of the regulator that have an output voltage higher than 4.5 V, the effective lower limit of VIN is VOUT plus the regulator’s dropout voltage, which varies approximately linearly with the load (see below for graphs of dropout voltages as a function of the load).\u003c\/p\u003e\n\u003cp\u003eThe output voltage, \u003cstrong\u003eVOUT\u003c\/strong\u003e, is fixed and depends on the regulator version: the D24V25F3 version outputs 3.3 V, the D24V25F5 version outputs 5 V, the D24V25F6 version outputs 6 V, the D24V25F7 version outputs 7.5 V, and the D24V5F9 version outputs 9 V.\u003c\/p\u003e\n\u003cp\u003eThe regulator is enabled by default: a 100 kΩ pull-up resistor on the board connects the \u003cstrong\u003eENABLE\u003c\/strong\u003e pin to reverse-protected VIN. The ENABLE pin can be driven low (under 0.6 V) to put the board into a low-power state. The quiescent current draw in this sleep mode is dominated by the current in the pull-up resistor from ENABLE to VIN and by the reverse-voltage protection circuit, which will draw between 10 µA and 20 µA per volt on VIN when ENABLE is held low.

Traditional power adapters can provide a wide range of current but the voltage stays fixed at 5V. With the SparkFun Power Delivery Board's USB-C connection it has the ability to achieve higher voltages, typically 5-20V and up to 100W of power. The Power Delivery Board uses a standalone controller to negotiate with the power adapters and have them switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output voltages. The Power Delivery Board is also part of SparkFun’s Qwiic connect system, so you won’t have to do any soldering to figure out how things are oriented.\u003c\/p\u003e\n\u003cp\u003eThe SparkFun Power Delivery Board takes advantage of the power delivery standard with the use of a standalone controller from STMicroelectronics, the STUSB4500. The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algorithm to allow the negotiation of a power delivery contract with a source (i.e. a power delivery wall wart or power adapter) without the need for an external microcontroller, although you will need a microcontroller to configure the board. PDO profiles are configured in an integrated non-volatile memory.

With the switch on the bottom of the board, you can set the common output voltages of 3.3V and 5V, but we've also added a custom setting that allows you to solder a resistor based on your custom voltage needs.
