  • 2 x 2 pin header
  • 1 x Battery Holder
  • 1 x battery (2032)
  • 2 x jumpers
  • 1 x 32.768 kHz crystal


It is best to start with soldering the crystal, then you do with the pin-headers and the socket on. In the end, assemble and solder the battery holder. The following figure describes the main components of this image you can be guided by the assembly.
