The Xadow product line is designed to be used in wearables and art installations, and places where you do not have the space for bigger designs. Different modules can be combined to make specialized solutions possible, and the mainboard options make Xadow systems usable in low power and computationally demanding situations alike. Instructions can be given via well known IDE's, and can easily be transferred to the mainboard via USB. Power consumption is very low, to improve battery life. The modules connect easily via standard FFC flat cable, and the connecting cables are very sturdy. You can use this product line to focus on the software and packaging, while not compromising on features!


  • Small & light When you don't want to keep noticing your hardware, or want to wear it.
  • Low power consumption We designed this product line with a focus on low power consumption, so you don't need to add a big battery.
  • Versatility Multiple main boards, so processing intensive projects can still be power-efficient.
  • Modular design & Easy to connect Make some easy connections, and your hardware design is ready!
  • High quality connections The bendable FFC cables make connections possible in many configurations and shapes.
