LM35 & Memory Card This is a little DIY project with an Arduino Uno, SD card breakout board, and LM35 temperature sensor. To build a temperature logger using a microSD card, just connect the LM35 ...

The Boombox’s main control board includes an Atmega328, an SD card socket, an mp3 decoder + D/A chip, and a level shifter to convert from 5V to the 3.3V required for the SD card and mp3 decoder.

Other boards use a similar socket and [Erich] identified it as an SD-105027-001 (PDF) from Molex–a dollar part. Soldering the socket on the board wasn’t too hard since the pads have some ...

A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...

Why would you make an SD card socket when you could buy one is unclear, beyond that he didn’t want to buy one on an Arduino shield and considered manufacture his only option.
