For electronics enthusiasts and makers, having a reliable and efficient power supply is crucial for any breadboard setup. Axiometa's BrodBoost-C is a USB Type-C breadboard power supply that delivers just that, combining simplicity, functionality, and power flexibility in one compact package.
Key Features of BrodBoost-C
The BrodBoost-C offers adjustable voltage from 3.3V to 5V
DC, making it suitable for a wide range of projects that require different
voltages. Whether you're working with 3.3V logic chips or 5V components, this
power supply can easily adapt to meet your needs.
The power supply can provide up to 1A of current,
ensuring that it can handle your moderate power requirements. Plus, the USB
Type-C connector ensures easy, modern connectivity to your power source,
eliminating the hassle of traditional barrel connectors or micro-USB ports.
Additional Features
- Dual
Rails: The BrodBoost-C powers both the power and ground rails of a
breadboard, so you won’t need separate power sources for each.
- On/Off
Switch & LED Indicator: A simple on/off switch, along with a red
power LED, lets you easily manage and monitor the power status.
- Safety
Features: The board is built with short circuit protection, and the
input features a ferrite bead for noise suppression and decoupling
capacitors to ensure smooth, noise-free operation.
- Built-in
Fuse Protection: This feature safeguards your breadboard and
components from unexpected power surges.
How It Works
The voltage regulation on the BrodBoost-C is straightforward
and efficient. The 5V output is selected by USB CC pins with 5.1 k
resistors, and for 3.3V, a step-down AMS1117-3.3 regulator is
used. This ensures stable output, even as your power needs change.

Open-Source Hardware
One of the standout features of the BrodBoost-C is that it
is fully open-source. Axiometa has released all the necessary documentation,
including KiCad schematics, PCB layouts, Gerbers, BoM
(Bill of Materials), and even a STEP file for the 3D model. This
allows makers to modify and customize the design to their specific needs or
build their own version of the board.
Pricing and Availability
The BrodBoost-C is currently available on Crowd Supply
with a funding goal of $5000. You can pledge $32 to receive one of these
breadboard power supplies, with free worldwide shipping. The expected
shipping date is July 11, 2025.
While the price may seem slightly higher compared to
alternatives like the XIAO Powerbread, which is priced at $19.99,
it's important to consider that the BrodBoost-C comes with added features like
fuse protection, adjustable voltage, and the benefit of being open-source.
Additionally, when purchasing alternatives, you might find yourself adding
extra costs for the boards or shipping.
The Axiometa BrodBoost-C is a solid choice for makers looking for a reliable, flexible, and safe power supply for their breadboard projects. Its adjustable voltage range, USB Type-C input, and open-source nature make it a great option for both beginners and seasoned electronics enthusiasts.
