Rev 1.4 hardware issue

Posted by Mirko Denecke on January 25, 2016 at 1:15pm

There is an issue with the Rev 1.4 boards. Input and output of the HC-SR04 voltage divider are swapped.

Rev 1.4 wrong:

Right:

3691270151?profile=original

This issue will be fixed with Rev 1.5. Please make sure to connect the HC-SR04 the right way.
