The design direction was corrected to a custom bare RP2350B board equivalent to the Pico Plus 2 architecture, with 16 MB QSPI flash, 8 MB PSRAM, USB-C, BQ24074 power-path charging, TPS63031 power conversion, MIDI I/O, buttons, OLED, and battery monitoring. Forty-two schematic components have been selected and added.
