HiLetgo Data Logger Module Logging Shield Data Recorder Shield for Arduino UNO wSD Card

Features: Onboard 3.3V regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run. Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported. Specification: Size: 68 x 53 x 23mm (approx) Regulator voltage: 3.3V Battery: CR1220 3V Note: This project does not come with an Arduino (you need to use a shield), or an SD card. 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. 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. 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.
