Sourcing

You will get complete kits with almost all parts already be soldered here for a donation. Some soldering skills are still neccessary.

Assembly

You should have following parts:

  • solder 01x07 2.54mm angled pin header to the NanoBCU on to the NanoBCU as shown - cut the pins before soldering!
  • solder J105 - 02x04 2.00mm THT pin header for connecting the front panel
  • solder J100 - solder pins for the KNX connector and J200 - 01x04 3.5mm THT screw terminal for I/O
cut the KNX pins as low as possible before soldering

  • solder the NanoBCU to the Controller2040
be carefull to solder it 90°!

  • configure the ribbon cable - press the IDC connectors with pliers or in a vice.
  • solder J1 - 02x04 2.00mm SMD pin header to the REG1-Front-Universal and break away the frame
  • connect Controller and Front with the ribbon cable
  • mount it into the REG1-Case
  • put the cover on the case and tighten the 6 screws gently
  • connect with a Micro-USB cable to your computer and load a firmware of your choice
