{"title":"SparkFun Power Delivery Board - USB-C (Qwiic)","handle":"sparkfun-power-delivery-board-usb-c-qwiic","url":"/products/sparkfun-power-delivery-board-usb-c-qwiic","description":"The SparkFun Power Delivery Board uses the STMicroelectronics STUSB4500 controller to negotiate USB Power Delivery (PD) contracts with compatible chargers and adapters. Instead of being limited to 5 V from a standard USB connection, this board can request higher voltages — typically 5–20 V and up to 100 W — from any USB-C PD power source.\n\nThe STUSB4500 handles all power negotiation autonomously using profiles stored in its built-in non-volatile memory. Configuration is done over I²C, and the Qwiic connectors make it easy to connect to a microcontroller for setup. Once configured, the board operates standalone — no microcontroller needed during normal use.\n\nKey Features\n\n\nUSB-C Power Delivery – Negotiate 5–20 V from PD-compatible adapters\n\nUp to 100 W – High-power output from a single USB-C connection\n\nSTUSB4500 Controller – Autonomous PD negotiation with NVM-stored profiles\n\nQwiic / I²C Interface – Solderless configuration via Qwiic connector\n\nStandalone Operation – No microcontroller required after initial configuration\n\nThrough-Hole Breakout – SDA and SCL plated through-holes for non-Qwiic setups\n\n\nSpecifications\n\n\nController: STMicroelectronics STUSB4500\n\nInput: USB-C (Power Delivery)\n\nNegotiable Voltages: 5–20 V (source dependent)\n\nMax Power: Up to 100 W\n\nConfiguration Interface: I²C (Qwiic or through-hole)\n\nProfile Storage: Non-volatile memory (NVM)\n\n\nIdeal For\n\nPowering projects from USB-C PD chargers at higher voltages\nReplacing multiple wall adapters with a single USB-C power source\nBattery charging systems that benefit from PD negotiation\nPortable and benchtop power supplies\n\n\nPackage Contents\n\n1× SparkFun Power Delivery Board – USB-C (Qwiic)\n\n\nResources\n\nHookup Guide\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4464,"title":"Default Title","sku":"SF-DEV-15801","price":62.75,"on_sale":false,"in_stock":true,"available_quantity":257,"option1":"Default Title"}]}
