Description

This kit supports 5.0V, 3.3V and 1.8V and all outputs can be used at the same time. This is very practical if multiple voltage sources are needed in a Breadboard Project.

The small form factor is designed to fit into most commonly used 2.54mm (0.1”) Breadboards.

The 5.0V output is unregulated and depends on the input voltage given from the connected USB device.

This Kit has been created for engineers, hackers and other technical people to simplify the circuit prototyping process and to always have a fitting USB power supply on hand.

Features

• Micro USB Connector
• Two Voltage Regulators
• Supports 5.0V, 3.3V and 1.8V at the same time
• 3.3V and 1.8V output with 300mA
• Maximum Output Power 2.5W
• Short Circuit Protection
• Over Temperature Protection
• High Ripple Rejection: 68dB @ f = 1kHz, 54dB @ f = 10kHz
• Small size: 20mm x 10mm

Outputs

• 5.0V @500mA ( unregulated )
• 3.3V @300mA
• 1.8V @300mA

Important Notes

• The Ground ( - ) of all outputs is always connected.
• The maximum current on the 3.3V and 1.8V outputs is 300mA each.
• The maximum current on the 5V output depends on the device where the USB is connected to. 
• This is a development kit made for people with technical knowledge, not for end users. 

Why did you make it?

I was getting frustrated with the fact that for every circuit i wanted to prototype or quickly build on a breadboard, i had to quite often waste time with building a power supply with the needed voltage first. The other common option of using a lab power supply i didn't like that much since it adds a lot of cabling and I quite often wanted to have multiple circuits running at the same time, but I don't have that many lab power supplies.

Another factor that made me create this board is the re-usability of it. I often built similar supply circuits with SMD adapters and a couple passive components, but it was not practical to take one supply circuit from one project to another, because it would have to be rewired anyways to take it from one breadboard to another.

What makes it special?

• It has a very small form factor while being able to output 5V, 3.3V and 1.8V at the same time
