About the Vinyl adc rev d PCB

Vinyl adc rev d is an open source Raspberry Pi PCB design by MadsRudolph, published on GitHub. It is a 4-layer board measuring 140 × 136 mm, with 177 components from 65 distinct parts.

Its main chip is the RASPBERRY PI 4, from the Raspberry Pi family. Other key parts include the 74HC244, LM358, 74HCT132, 74HC4040 and 74HC157. By type, the board carries 69 resistors, 52 capacitors, 20 ICs, 16 diodes, 10 connectors and 3 transistors.

It belongs with the audio designs in this gallery.

Discrete 3rd-order delta-sigma audio ADC: stacked KiCad PCBs, SPICE simulations, 3D-printable enclosure, and laser-cut acrylic top

Rev C showed that a fab removes the reason the converter was ever split into four milled boards. Rev D is the board designed for a fab — PCBWay offered to make it — rather than merely allowed by one: 140 × 136 mm, four layers, every part through-hole and (with one optional exception) from the DTU shop, the Raspberry Pi 4 plugged into a 2×20 socket on the copper side HAT-style. Rev C's placement was discarded; the circuit was not. Its SMD twin, the same circuit in distributor parts on 118 × 88 mm, is rev E (../reve/). The sheet is drawn by the same block functions as the reference sheet and…

Vinyl adc rev d: common questions

What microcontroller does the Vinyl adc rev d use?

The Vinyl adc rev d is built around the RASPBERRY PI 4, from the Raspberry Pi family.

How big is the Vinyl adc rev d PCB?

The Vinyl adc rev d measures 140 × 136 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Vinyl adc rev d?

177 components, from 65 distinct parts. The full bill of materials is listed on this page.

Where can I download the Vinyl adc rev d design files?

From the MadsRudolph/vinyl-adc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Vinyl adc rev d design in my own project?

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

Can I test firmware for the Vinyl adc rev d without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
