Keyestudio Expansion Board+TF Card for Data Recording)

The Keyestudio Expansion Board with TF Card is a dedicated data logging shield designed for students, educators, and makers using the Arduino Uno. It combines real-time timekeeping with secure storage, making it easy to record and analyse sensor data over time. This shield is perfect for environmental monitoring, weather stations, and DIY science experiments.

Precise timekeeping with onboard RTC

The expansion board features a built-in DS1307z Real-Time Clock (RTC) chip to keep accurate track of time. This allows you to timestamp your sensor readings and data logs for precise follow-up studies.

Seamless TF card data logging

Equipped with an integrated TF card interface, this shield lets you save information detected by your microcontroller directly to a TF card. It simplifies the process of recording long-term environmental or experimental data.

Built-in prototyping area

To facilitate custom expansions, the board features circular welding holes spaced at a standard 2.54mm pitch. This allows you to easily solder additional sensors and components directly to the shield.

Dedicated Arduino Uno compatibility

This expansion board is designed specifically to fit and function with Arduino Uno control boards. It plugs directly on top of your Uno to create a compact, self-contained data logging system.

Electrical and operating specifications

Operating at 5V DC with a low 60mA current, this board consumes a maximum of 0.3W. It functions reliably in temperatures ranging from -10 degrees Celsius to +50 degrees Celsius and requires a CR1220 battery for the RTC.
