Elec Ventouse 3d: common questions

What microcontroller does the Elec Ventouse 3d use?

The Elec Ventouse 3d is built around the Pico 2, from the RP2040/RP2350 family.

How big is the Elec Ventouse 3d PCB?

The Elec Ventouse 3d measures 45 × 64 mm, has 4 copper layers and is 1.566 mm thick.

How many components are on the Elec Ventouse 3d?

132 components, from 43 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 Elec Ventouse 3d design files?

From the pollen-robotics/elec_Ventouse_3d 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 Elec Ventouse 3d design in my own project?

Yes, under the terms of its Apache-2.0 license, which pollen-robotics chose for the repository.

Can I test firmware for the Elec Ventouse 3d 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.
