Its main chip is the RP2040_QFN56, from the RP2040/RP2350 family. Other key parts include the LSM6DSOXTR, 8MB QSPI, RT9080-3.3, MCP73831T-2ACI/OT and MAX98357A. By type, the board carries 29 capacitors, 23 resistors, 7 ICs, 4 transistors, 4 inductors and 3 crystals.

It belongs with the audio designs in this gallery.

From the project

A software and hardware project to create a digital handbell using microcontrollers and speakers and gesture recognition

Later placement alternative: the separate wing draft adds selective rear-face population and M2 mounting interfaces for the integrated cartridge. This directory's original 0.2 CAD and print snapshot remain unchanged; open the variant's project for the newer placement.

Reduced electronics and a 43 mm unrouted candidate; not a fabrication release. Open handbell.kicadpro in KiCad 10.0.6, then its schematic. For a CAD-free view, use the schematic PDF. The PCB editor opens handbell.kicadpcb, an actual-footprint placement with no tracks/vias/zones. Start with the 0.2 handoff for boost, mute…
