About the MicroSD to DIP Breakout 74HC4050
MicroSD to DIP Breakout 74HC4050 is an open source PCB design by vul-os, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 30.5 × 20.3 mm, with 7 components from 6 distinct parts.
Other key parts include the AP2127K-3.3 and 4050. By type, the board carries 2 ICs, 2 capacitors, 1 connector and 1 resistor.
It belongs with the dev boards & breakouts, sensors and usb & debug tools designs in this gallery.
From the project
Open hardware: 107 KiCad PCB designs — SMD-to-THT breakout adapters, ATTiny/ATMega/ESP development boards, and a 39-part sensor line on a common JST-SH connector.
The mark in brand/ is the source of truth. Every icon this repo ships — favicon, PWA and app icons, the mark in the README and on the site — is rendered from brand/logo.svg rather than redrawn, so there is one approved drawing and no second copy to drift.
Copy it outward, never edit a derived copy, and never edit brand/ to match something downstream.
Most interesting silicon ships in a package that will not sit on a breadboard. SirBoard answers that in three layers: bare adapters you solder the part onto yourself, modules with the part already placed and supported, and development boards…
