Application Board for R8C/13

Base camp for high Endeavour’s

Application Board for R8C/13
In the February issue, we described how you can get started with the R8C/13 microcontroller module without all too much effort. The application board described here gives the module a ‘base camp’ with lots of connections to the outside world, including a USB interface and two serial ports. There’s also an LCD interface and other useful features for developing your own applications.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor 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 its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.
