HiLetgo Data Logger Module Logging Shield Data Recorder Shield for Arduino UNO w/SD Card
<b>Features:</b><br> Onboard 3.3V regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run.<br> Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher.<br> ADK/Mega R2 or lower are not supported.<br><br> <b>Specification:</b><br> Size: 68 x 53 x 23mm (approx)<br> Regulator voltage: 3.3V<br> Battery: CR1220 3V<br><br> <b>Note:</b><br> This project does not come with an Arduino (you need to use a shield), or an SD card.<br> The package doesn't contain with RTC battery, but now all the components of the geothermal fire are soldered and tested, but no head mounted.<br> You need some basic soldering skills to put it together, but even if you do not have much experience you can get it done in 15 minutes.<br>The SDA/SCL pins (next to the reset button) are not connected. If you use a board other than R3, you need to connect the A4/A5 pins to proper SDA/SCL pins manually.<br> <br> <b>Document:</b><br>https://learn.adafruit.com/downloads/pdf/adafruit-data-logger-shield.pdf <br> <br> <b>Package Included:</b><br> 1*Mini Logging Recorder Data Logger Module
