1. Electronic clock function. Four digital tube display time function. Every second, digital tube, two points on a flashing, at the same time, the casing outside the clock LED will take turns to light up a take turns bright finish a circle represents the clock through a minute 2. Date display. Through the key switch, you can see the preset date. Specific look at the following keys function description 3. Alarm function. Through the button switch, you can set the alarm clock function. When to set the alarm time, buzzer sounds, if not, manually turn off the buzzer will continue to ring for 10 minutes. Specific look at the following keys function description 4. Burning function. The reserved buffer program interface, can change to the circuit board to do procedure, easy to operate 5. Real time clock function. Tone after a preset time, even if the power lost, again after power on, no need to set a time 6. Temperature display function. Under the time display mode, press PLUS, can display the current temperature 7. Many mode display function. Outer LED display has four modes, can cooperate to add key implementation, through the model key Mode 0: is also the default display mode, all the 1-12 hours red digital tube light, when the clock through a second, is the green digital tube is take turns to light up a. Mode 1: as the clock through a second, outer ring LED lit one by one, that is 60 seconds, outer ring all the LED light. The next minute, all leds light up, and through the clock for a second, put out one by one. And the next minute, leds light up one by one again, so alternates. Mode 2: when the clock through a second, outer ring take turns to light up a LED. The first seconds, only the first LED light, 2 seconds only the second LED light. Mode 3: when the clock through a second, outer LED turns off a. The first seconds, only the first LED out, only the second LED out 2 seconds. Key Function: PLUS key, for years, months, days, hours, minutes, seconds add operation. According to the numerical sum 1 at a time MODE key, can be in display clock, switch to the year, month, day, hours, minutes, alarm clock, the adjustment of outer ring LED display state. To use add key to the year, month, day, hours, minutes, seconds, and display mode to adjust RST key, press the reset button, then the MCU reset Specification: Size: 81mm x 81mm x 1.6mm / 3.18 * 3.18 * 0.06" PCB thickness: 1.6mm / 0.06" Material: FR4 military level PCB color: Blue Digital Tube display: Red Power supply voltage: mini USB, external connection 5V, 3V button battery for clock chip on the board of the standby power supply Package includes: 1x Rotation LED Electronic Clock DIY Kit |

NOTE : we NOT offer any battery !!! Dimension: Length: 40.2mm,Width: 12.8mm,Thickness: 14mm Operating voltage:3V~5V (Note:the voltage is lower , lower brightness, lower power consumption) Four display modes: 1 only display time 2 only display the Voltage 3 only display temperature 4 display the time, Voltage, temperature alternately With temperature display function,display range:-9~60°C , With temperature error correction,Range is -5 °C to 5 °C With 24h timing error correction,Range is -9 to 9 seconds. (Note:To make the function take effect,required 24 hours of continuous power supply, that is,working 24 hours before correcting the erroronce) The DS1302 chip timing comes with a back up CR1220 battery, power-down time to continue to walk Crystal Accuracy: 5ppm Package Included: 1 x 0.36" Led Digital Display Electronic Time Clock DS1302 |
