Package Included

- 1 x DS1302 Real Time Clock Module
  (CR2032 Battery not included)

Description:

- DS1302 is introduced trickle charge the clock chip,.
- A clock can be done by the AM / PM or 12 decided to use 24-hour format. Between the DS1302 and the microcontroller can simply use the synchronous serial communication mode, used only three port lines: (1) RST Reset (2) I / O data lines (3) SCLK serial clock. Clock / RAM read/write data to a byte or up to 31 bytes of character
set way communication. DS1302 low-power work to maintain the data and clock information when power is less than 1mW
- Operating temperature: 0-- 70
- Wiring (to provide the program, for example, can take any IO port, the port defined in the program can be modified):

VCC → +5 V/3.3V
GND → GND
CLK → P02
DAT → P01
RST → P00
