VolPak-1000: common questions
What microcontroller does the VolPak-1000 use?
The VolPak-1000 is built around the ESP32-S3, from the ESP32 family.
How big is the VolPak-1000 PCB?
The VolPak-1000 measures 153.7 × 108.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the VolPak-1000?
185 components, from 81 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 VolPak-1000 design files?
From the raybello/KICAD-PCBs 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 VolPak-1000 design in my own project?
The repository has no license, so all rights stay with raybello. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VolPak-1000 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.
