When we conduct DIY experiments, we tend to connect some sensors with Arduino microcontroller to detect all kinds of data. And we will need to save these data and record the saving time for follow-up studies. Therefore, we have designed this expansion board to simplify this process.
First, this board boasts a DS1307z RTC (Real-Time Clock) chip to keep track of time. Second, the built-in TF card interface can connect with a TF card, which makes saving the information detected by the UNO board possible.Furthermore, to facilitate its expansion function, the board is equipped with circular welding holes with spacing of 2.54mm.
Please notice that this expansion board is only compatible with UNO control boards.
