描述

SparkFun Power Delivery Board – USB-C (Qwiic) 電源管理板最高輸出 5A

SparkFun Power Delivery Board 現在是時候有效地管理項目中的電源分配了，有了SparkFun Power Delivery Board，您可以！傳統電源適配器可以提供寬範圍的電流，但電壓保持固定在5V。借助SparkFun電力輸送板的USB-C連接，它能夠獲得更高的電壓，通常為5-20V，最高功率為100W。配電板使用獨立的控制器與電源適配器協商，並使其切換到5V以外的更高電壓。這將相同的電源適配器用於不同的項目，而不是依賴多個電源適配器來提供不同的輸出電壓。供電板也是SparkFun的Qwiic連接系統的一部分，因此您無需進行任何焊接就可以確定事物的方向。

SparkFun電力傳輸板通過使用意法半導體的獨立控制器STUSB4500來利用電力傳輸標準。STUSB4500是一個USB供電控制器，用於處理宿設備。它實現了專有算法，無需外部微控制器即可與電源（即壁裝電源適配器或電源適配器）協商電源供應合同，儘管您將需要微控制器來配置電路板。PDO配置文件配置在集成的非易失性存儲器中。控制器完成了電源協商的所有繁重工作，並提供了一種在I ² C上進行配置的簡便方法。

要配置該板，您將需要I ² C總線。Qwiic系統使將電源傳輸板輕鬆連接到微控制器變得很容易。根據您的應用，還可以通過SDA和SCL的鍍通孔連接到I ² C總線。

SparkFun Power Delivery Board – USB-C (Qwiic)

It’s time to effectively manage the power distribution into your project and with the SparkFun Power Delivery Board, you can! 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.

The 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. The controller does all the heavy lifting of power negotiation and provides an easy way to configure over I²C.

To configure the board, you will need an I²C bus. The Qwiic system makes it easy to connect the Power Delivery board to a microcontroller. Depending on your application, you can also connect to the I²C bus via the plated through holes for SDA and SCL.
