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.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Power Delivery Board - USB-C (Qwiic) Hookup Guide

February 13, 2020

This guide will go over how to use the USB Type-C Power Delivery Board.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

  • Can the D-/D+ pins be passed on to another board of yours to end up with serial? I bought one of the CH boards but despite passing a loopback wire test, it is unable to communicate with my supposedly 3.3V device I had no trouble talking to an RPI with. I'm looking for alternatives and figured while I'm at it, I might as well source power.

    • D- and D+ are just regular USB 1/2, and you can't get serial directly from them. You'd need to connect a USB to serial converter to them to get TTL serial.

  • This looks slick as snot, but without a power supply it's just a paper weight. Where's the links to the USB-C power supply with power delivery sold by Sparkfun that actually powers this thing?

    • I'd have to double check, but I think we took them down due to the issue with the Raspberry Pi USB-C issue. However, as @Jason33 mentions, you can by them at your local electronics retailer.

    • Although I don't disagree it would be nice to have the option to purchase a compatible power supply from SparkFun; PD chargers have been on the market for a decent amount of time (relative to new tech). Your big box stores as well as plenty of online retailers have plenty to choose from. Personally I've got a few combo USB A + C bricks from Monoprice as well as a Type-C PD cigarette/car adapter that I love. I'd rather SparkFun keep their stock, shelves, and personal focused on delivering unique custom products like this and only supply power adapters for common sense/safety like 2.1mm/2.5mm barrel plug stuff where they shop around and guarantee it uses a sensible ground to help us avoid ground loops.
