Description
Specifications:
- PCB a single panel, size: 42mm x 24mm x 1.6mm(max)
- with 4 holes, about 3.1mm in diameter
- Color: green (as the picture shows)
- genuine spare battery for the celestial sphere CR2032, Voltage 3V, current is 260mAh, non-rechargeable batteries.
- Crystal 32.768KHz, matching capacitance 6pF, size 2 * 6mm
- DS1302 made large 8-pin DIP chip, chip, IC Block below for easy replacement and plug the chip
- module operating voltage compatible 3.3V/5V, 5V and 3.3V microcontrollers can be connected with 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
- 1.51 MCU P0 port requires a pull-up, if your single-chip pull-up resistor is not connected, you can port the data cable to the other
- 2VCC and GND must not be reversed, or it will burn the chip
Packing List:
1 x DS1302 Real-Time Clock Module
