SD card datalogger shield for Arduino with two external voltage references.
I've made this shield because there were no designs in the wild employing external references - this is usefull feature to have when logging analog voltages.
Features:
- 74hc125 buffer for level translation
- 1.20V voltage reference selectable via solder jumper
- 2.5V voltage reference selectable via solder jumper
- red indication led
- green indication led
- SD card detection
- SD card write protection detection

Questions
How big is the Sdcard shield PCB?
It measures 58.4 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sdcard shield use?
24 parts, built around the 74LS125DC, ISL60002BIH311Z-TK and JUMPER3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Sdcard shield KiCad files?
From the Miceuz/ArduinoDataloggerShield repository on GitHub, at the commit this page was made from: the board is sdcard-shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sdcard shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask Miceuz before reusing the design.
