VCO PCB B REV2: common questions
What microcontroller does the VCO PCB B REV2 use?
The VCO PCB B REV2 is built around the RP2040, from the RP2040/RP2350 family.
How big is the VCO PCB B REV2?
The VCO PCB B REV2 measures 81.3 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the VCO PCB B REV2?
52 components, from 34 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 VCO PCB B REV2 design files?
From the gfm16617/EngrEDU_Website 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 VCO PCB B REV2 design in my own project?
The repository has no license, so all rights stay with gfm16617. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VCO PCB B REV2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
