Axiometa, a Lithuania-based open-source hardware team, is introducing BreadBoost-C, a compact USB Type-C-powered solution for breadboard prototyping. Designed for makers, educators, and engineers, BreadBoost-C simplifies circuit prototyping by eliminating messy wiring and bulky bench power supplies.
The device offers adjustable output voltages of 3.3 V or 5 V, a 1 A maximum current, and built-in short-circuit protection. Features include independent rail voltage adjustment, a power switch, an LED indicator, and breadboard-compatible headers. It’s particularly useful for low-power IoT, embedded systems, and portable prototyping.
While its use of an AMS1117-3.3 linear regulator may raise concerns about efficiency in battery-powered scenarios, BreadBoost-C’s simplicity and focus on essential features make it a valuable tool. From the schematics it also seems that the board does not support USB-PD, so support with the latest power adapters might be limited. Axiometa plans to share its open-source designs, encouraging innovation and accessibility in the electronics community.
