Data Logging Expansion Shield With RTC Clock & TF Card Storage

This data logging expansion shield integrates RTC real-time clock unit and TF card slot with CR1220 battery holder to keep accurate timestamp even after power off. A large prototyping perf board area is reserved for self-soldering small peripheral circuits. Fully extended universal IO pins match common 8-bit main control boards, working with temperature, humidity, light and pressure sensors for timing data collection & offline local storage. Built-in reset button with stable circuit layout. Widely used in environment monitoring, greenhouse data recording, equipment log collection, university timing electronics training and offline IoT recording projects.
