PCB Calender V2

This is an Arabic desk calendar based on the ESP12-F chip. It takes time and date from the online server. No RTC is used.

For driving tons of LEDs I used 74HC595 shift register IC. 

For programming the ESP chip, the 5-pin is left on the bottom side. There are 4 buttons on the bottom side. One is the reset button, one for booting the chip and two others for manually adjusting the time and date. 

The calendar will take power through a micro USB port. 

Details are coming...
