Ad low noise float 2023 git: common questions

What microcontroller does the Ad low noise float 2023 git use?

The Ad low noise float 2023 git is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the Ad low noise float 2023 git PCB?

The Ad low noise float 2023 git measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ad low noise float 2023 git?

237 components, from 71 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 Ad low noise float 2023 git design files?

From the petermaerki/ad_low_noise_float_2023_git 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 Ad low noise float 2023 git design in my own project?

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

Can I test firmware for the Ad low noise float 2023 git 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.
