> > | It is possible to mount the PCB direct onto the wheel spokes but it is
better to use a mounting frame. This frame can be ordered from
http://shapeways.com or you can print it by yourself on 3D printer.
The Printed Circuit Board (PCB) is free hardware. The PCB is a multi-layer (4 layer) 160 x 30.5 x 1.6 mm FR4 board. The firmware for the MK22DX256VLF5 MCU is also on GitHub.
There is also an optional Bluetooth Low Energy (Smart) subsystem on board.
It is a LAIRD BL600-SA module. The Bluetooth application software is on
GitHub too.

With this edition you can at least view and print the drawings. The Design exceeds the limits (100 x 80 mm board size) for the Light Edition, therefore you can not edit/change the design. There is also EAGLE Make Personal edition, with this edition you can edit the design for about 140 € (only for non commercial use). See EAGLE Pricing Table for other licenses. Maybe the free KiCad can be used to import the design.How To Build or Order FramesI ordered my frames from PCB-POOL, they accept the EAGLE design files (e.g.ewheel32.brd ) and you do not have to generate you own Gerber and Excellon drill files.
