• RP2040 Dual Core Cortex M0+ running at up to 400MHz
  • USB Type-C connector
  • 2MB Flash for Firmware and Data
  • Very low noise LDO regulators (separate LDO for digital circuits and separate for analog circuits), no switching regulators
  • Partially pin-compatible with RP2040 (besides a few pins internally used or rearranged), extra 4 pins on each side
  • Audio DAC PCM5100A, up to 32-bit output
  • Very high audio signal quality and very low noise
  • Dedicated Boot and Reset Buttons
  • 8 channel 12-bit ADC with up to 1MS/s, with selectable 3.3V range (on-board low-noise power supply) or range up to 5V via external VREF
  • Low-Pass filter on each ADC input (fMax=48 KHz) at low-impedance (100 Ohm). With 5V VREF suitable for CV (no overvoltage protection, unipolar)
  • Symbols marking special pin functions on the pin headers
  • 4 LEDs on shared GPIO2-5 for debugging
  • ESD Protection on USB
  • SWD Debug Port
