We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focus on very different areas. Compared with Arduino, the Pi gets much better computing performance.
This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it require..
The DS1307 Real Time Clock developed by one of the DFRobot designers: Waiman. The module comes fully assembled and pre-programmed with the MST current time. The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimum of 9 years (17 years typical) without external 5V..
