Application Board for R8C/13
Base camp for high Endeavour’s
Published in issue 352, March 2006
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.
