It's a fully assembled and programmed PCB with 2.13" e-paper display - a heart of Agora Clock or Agora Watch. But you can also create you own variation. For inspiration check my homepage: www.agorawatch.com
Just connect a bench power supply or a Li-ion or Li-pol battery and you have a working clock. Then you can start experimenting with firmware or just put it in some box and enjoy the e-paper display.
For minimal functionality just connect the e-paper display and Li-ion battery or regulated power supply to B+ and GND pins. The voltage should be between 3.3V and 5V. When the Li-ion (or Li-pol) accumulator is connected, it can be charged using VIN and GND pins. The charging current is limited to 100 mA. If you need to connect external buttons you can use the B1-4 pins (connect the button between the B1-4 pin and GND). You can also use LED+ and LED- for external LEDs, but pay attention – you need to add current limiting resistor.
There is also a pair of pins for vibration motor/buzzer. This output has a build-in current limiting resistor. The LED and MOT output are open-drain type so they can be used also for other purposes.
