From the project

3 channel bench supply with current and voltage plotting

Integrated hardware and firmware repository for the development-station bench supply, its control electronics, front-panel display path, and supporting boards.

This is the active working repo for the full bench-supply platform, not just a single firmware target. It currently includes:

- ESP32 control firmware - DSP regulator board design - DSP regulator HAT / measurement-control board design - original front-panel display board files - USB hub board files and next-iter reference cleanup - bring-up notes, pin maps, and display evaluation references

DSP-Regulator-HAT-RevB: common questions

What microcontroller does the DSP-Regulator-HAT-RevB use?

The DSP-Regulator-HAT-RevB is built around the STM32_BLUE -, from the STM32 family.

How big is the DSP-Regulator-HAT-RevB?

The DSP-Regulator-HAT-RevB measures 100 × 102.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DSP-Regulator-HAT-RevB?

158 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the DSP-Regulator-HAT-RevB design files?

From the Phil-CIA/Development-Station-Power-Supply repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DSP-Regulator-HAT-RevB design in my own project?

The repository has no license, so all rights stay with Phil-CIA. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the DSP-Regulator-HAT-RevB without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
