VNTR-65: common questions

What microcontroller does the VNTR-65 use?

The VNTR-65 is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the VNTR-65 PCB?

The VNTR-65 measures 370 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the VNTR-65?

126 components, from 24 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 VNTR-65 design files?

From the FanieVenter/VNTR-65 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 VNTR-65 design in my own project?

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

Can I test firmware for the VNTR-65 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.
