What is it?

Power your next project the smart way – with this versatile USB-C PD trigger board! It lets you pull exactly the voltage and current you need from a USB-C Power Delivery power supply – no fuss, no coding, no waiting. Just turn the two onboard rotary switches to choose your desired voltage (5–20 V) and current limit (1–5 A), and the onboard CYPD3177 controller does the rest.

Forget fiddly barrel jacks or fixed-voltage adapters – this board gives you fast, flexible, tool-free power in seconds. Thanks to the Wago-style lever terminal, you can connect your wires securely and effortlessly, with no crimping or screwing required.

It’s compact, clearly labeled, and packed with features to make prototyping, development, and testing easier than ever.

Why did you make it?

Modern USB-C PD chargers are compact and powerful – but most devices only use a fraction of their capabilities. I wanted a way to fully unlock the potential of USB-C PD to power a wide range of hardware in my lab, from microcontrollers to motor drivers. This board is the result: a flexible, reliable power solution that fits in your pocket and replaces a whole stack of wall warts and power bricks.

What makes it special?

This isn’t just another fixed-voltage PD trigger. It’s your personal power configurator:

• Selectable voltage & current limit via rotary switches – no jumpers, no firmware flashing

• Wago-style terminal – connect wires instantly without tools

• Real-time feedback

• PG LED confirms the PD controller is up and running

• Fault LED alerts you when the requested voltage/current combo can’t be delivered

• Compact & rugged – ideal for mobile labs, test setups, field use, or anywhere flexible power is needed

• Trusted Cypress PD controller (CYPD3177) – no sketchy handshake hacks here

Whether you're powering a Raspberry Pi, ESP32 board, LED strip, or a custom PCB – this board makes USB-C your go-to power source.
