About the DAC2932 PCB

DAC2932 is an open source RP2040/RP2350 PCB design by kelu124, published on GitHub. It is a 2-layer board measuring 85.5 × 54 mm, with 42 components from 16 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the DAC2932PFBT. By type, the board carries 15 resistors, 14 capacitors, 9 connectors, 2 ICs and 2 inductors.

From the project

A rp2040 controlled fast DAC with 2 fast, 4 slower 12 bits outputs (DAC2932)

The DAC2932 devboard is a simple yet powerful tool for anyone working with high-speed digital-to-analog conversion (DAC). Designed for ease of use, it combines a high dynamic range with low power consumption, making it a great choice for engineers and hobbyists alike.

At its core, the DAC2932 features dual 12-bit DACs capable of delivering up to 40 million samples per second (MSPS), as well as four additional voltage-output DACs operating at around 1 MSPS. The entire setup is controlled by a Raspberry Pi Pico (RP2040), meaning you don’t need any complex FPGA programming. The open-source…

DAC2932: common questions

What microcontroller does the DAC2932 use?

The DAC2932 is built around the Pico, from the RP2040/RP2350 family.

How big is the DAC2932 PCB?

The DAC2932 measures 85.5 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DAC2932?

42 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the DAC2932 design files?

From the kelu124/DAC2932 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DAC2932 design in my own project?

The repository has no license, so all rights stay with kelu124. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the DAC2932 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.
