One ordinary off-contact via and a short F connection restore the shared C6/C7/C8/C13/C17 ground island to In1 MAIN, with no placement or existing copper changes. The acceptance record binds validation and Astra's filled-layer review. Exact CAD rebinding is required; the prior completed IMU CAD is preserved, not relabeled as a…

C23-usbboot staged: common questions
What microcontroller does the C23-usbboot staged use?
The C23-usbboot staged is built around the RP2040, from the RP2040/RP2350 family.
How big is the C23-usbboot staged PCB?
The C23-usbboot staged measures 44.5 × 48.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the C23-usbboot staged?
84 components, from 45 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 C23-usbboot staged design files?
From the dcuccia/digital-handbell repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the C23-usbboot staged design in my own project?
Yes, under the terms of its MIT license, which dcuccia chose for the repository.
Can I test firmware for the C23-usbboot staged 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.
