Local prewired: common questions
What microcontroller does the Local prewired use?
The Local prewired is built around the RP2040, from the RP2040/RP2350 family.
How big is the Local prewired PCB?
The Local prewired measures 90 × 70 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Local prewired?
58 components, from 27 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 Local prewired design files?
From the JesseLevine727/AirNote repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Local prewired design in my own project?
The repository has no license, so all rights stay with JesseLevine727. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Local prewired 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.
