Iso adc cvm: common questions

What microcontroller does the Iso adc cvm use?

The Iso adc cvm is built around the Pico, from the RP2040/RP2350 family.

How big is the Iso adc cvm PCB?

The Iso adc cvm measures 123.3 × 143.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iso adc cvm?

175 components, from 32 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 Iso adc cvm design files?

From the OisinS13/FC_IP_rig 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 Iso adc cvm design in my own project?

Yes, under the terms of its GPL-3.0 license, which OisinS13 chose for the repository.

Can I test firmware for the Iso adc cvm 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.
