Kicad pulse supply rev-B: common questions
What microcontroller does the Kicad pulse supply rev-B use?
The Kicad pulse supply rev-B is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Kicad pulse supply rev-B PCB?
The Kicad pulse supply rev-B measures 127 × 96.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Kicad pulse supply rev-B?
176 components, from 82 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Kicad pulse supply rev-B design files?
From the adilet2109/current-sensor repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Kicad pulse supply rev-B design in my own project?
The repository has no license, so all rights stay with adilet2109. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kicad pulse supply rev-B without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
