About the Rp2040-business card PCB

Rp2040-business card is an open source RP2040/RP2350 PCB design by rsheldiii, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 37.8 × 32.5 mm, with 47 components from 24 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the NCP1117-3.3_SOT223, W25Q128JVS, ST7735s_8 and MAX98357AETE+T. By type, the board carries 21 capacitors, 13 resistors, 5 ICs, 3 diodes, 2 connectors and 1 crystal.

It belongs with the audio designs in this gallery.

From the project

The Doom Stamp was based off the RP2040 Minimal Design Example, and is designed as a platform to make embedded devices that run Doom (or indeed, embedded devices with i2s audio and SPI displays).
