DS1302(without battery) is introduced trickle charge the clock chip, containing a real-time clock / calendar and 31 bytes of static RAM, via a simple serial interface
to communicate with the microcontroller. Real-time clock / calendar circuit provides seconds, minutes, hours, days, weeks, months, years ofinformation, the number of days per month and leap year automatically adjust the number of days. 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
Real time clock with the year 2100 to calculate the seconds, minutes, hours, days, weeks, months, years, the ability, as well as the ability to leap
year adjustment
1.31 8 temporary data storage RAM
2.Serial I / O port pin makes the least number of ways
3.Wide range of operating voltage 2.0 5.5V
4.Current 2.0V, less than 300nA
5.Read / write clock or RAM data transmission when there are two single-byte transmit and multi-byte character sets transfer mode
6.8-pin DIP package or optional 8-pin SOIC package assembly according to the surface
7.simple 3-wire interface
8.Vcc = 5V and TTL-compatible
9.Optional industrial temperature range -40 to +85
10.Dual power tube for the main power and backup power supply
Parameters:
1.PCB a single panel, size: 42mm * 24mm * 12mm(max)
Net weight:10g
Package weight:20g
Color:green (as the picture shows)
2 with 4 holes, about 3.1mm in diameter
3 genuine spare battery for the celestial sphere CR2032, Voltage 3V, current is 260mAh, non-rechargeable batteries.
4 Crystal 32.768KHz, matching capacitance 6pF, size 2 * 6mm
5.DS1302 made large 8-pin DIP chip, chip, IC Block below for easy replacement and plug the chip
6 module operating voltage compatible 3.3V/5V, 5V and 3.3V microcontrollers can be connected with
7 Operating temperature: 0 --- 70
NOTE:
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.VCC and GND must not be reversed, or it will burn the chip
2.51 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

I Exclusively Use ONLY Hiipoo Products - Simply the BEST!
Size: 120g 8.5" x 11"
I'm just about to purchase this product for the 3rd time. I simply cannot believe how well this product works for me. In the past, I had a $2k Ricoh sublimation printer, using Sawgrass ink, and specialty sublimation paper. That expensive Ricoh printer didn't last over 2 years. I took such great care of that machine, and it was terrible. Now, I use an Epson-2800, and I ONLY USE Hiipoo ink and paper, because it is THE BEST! Hiipoo inks work excellent in Epson printers, but you must initially start with their ink, you cannot add the ink to whatever you already have in your printer. This paper is compatible with Epson printers. I will exclusively only use Hiipoo products. The quality is unmatched. The performance is superior. The value is outstanding. I HIGHLY recommend Hiipoo products. I am not a paid spokesperson, not do I receive compensation for this review. I just own a business that provides laser engraving and sublimation printed items. You cannot go wrong using this sublimation paper. Buy their inks too, the quality of the printed items are exceptional. Excellent thickness of paper. It's durable, dries quickly and the color quality is excellent! Love Hiipoo products!!!

Great paper!
Size: 120g 8.5" x 11"
I love Hiipoo sublimation paper!Colors come out crisp and clear. And so bright and beautiful! The pattern on the back is a real big plus also. This paper is great quality, not flimsy, thick enough that it's easy to use and printers don't have problems picking it up.

Quality Paper Gives Great Results
Size: 120g 8.5" x 11"
Works well for Sublimation done thru Ink Jet Printers. Quality material and the finished heating provided great results in my projects. I used in conjunction with the Hiipoo Sublimation Ink and they made beautiful results with no issues. Thank you.
