Elektor mbed Interface
CoCo-ri-Co in the cloud
The extended open source library together with free online code editor and compiler suite made available by ARM (or must we now say Softbank?) as the fast prototyping platform mbed is an excellent tool for developing powerful applications on third-party hardware. But did you know that it is also possible to create your own mbed enabled hardware and add drag ‘n’ drop programming to your design?
Materials
Gerber file
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
