It outputs 1-32V at up to 3A (~92W from a 100W PD source), supports software-controlled switching, voltage/current measurement, and power cycling of a device under test. It runs on an STM32G0C1CEU microcontroller, is controlled via SCPI commands over USB (compatible with Python, VISA tools, or custom scripts), and integrates with the HardPy framework. Hardware design files, firmware, and software will be open-sourced under CERN-OHL-W-2.0, Apache 2.0, and CC BY 4.0 licenses. It's live on Crowd Supply with a $3,000 goal, priced at $230 per unit, shipping around March 2027. ## Full article daily.dev links to this article rather than hosting it.
