General • Pi 2040 components for ADK upgrade

Hi, I would like some advice on hardware components for adding funtionality of a Pi 2040 ADK. I have a RP2040 and would like to know how possible this is to breadboard and prototype a circuit for these components.


Here is a list components from ADK link below, which I have already. I couldn't find a schematic for it.

1×PCM5100A DAC
1×ADC128S102 ADC
1×RP2040

Here is the spec from Github:

RP2040 Dual Core Cortex M0+ running at up to 400MHz (overclocked)
USB Type-C connector (Host & Device Mode)
2MB Flash for Firmware and Data (4MB on v1.1b)
Very low noise LDO regulators with 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 for SPI ADC
Audio DAC PCM5100A, up to 32-bit high-quality output
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 with external 5V voltage reference input suitable for CV (no overvoltage protection, unipolar)
Symbols marking special pin functions on the pin headers
4 LEDs on shared GPIO2-5 for debugging, 1 RGB WS2812B LED
ESD Protection on USB
SWD Debug Header
JST 1.0mm 4 Pin (QWIIC compatible) I2C Connector
