I recently purchased the GP2Y0D810 digital proximity sensor from Pololu robotics to use with a obstacle avoiding robotic system. These digital sensors is designed to detec objects within 10cm. It does not tell how far the object is but senses if there is something within 10cm range. More information about the sensors can be found on Pololu store web site. Pololu also sells the carrier board for the sensor. I decided not to buy those and design my own carrier board as the board circuit looked quite simple and straight forward. I use the non-commercial evaluation version of Eagle CAD for PCB designs. The challenge was to find a ready made library for the GP2Y0D810 part. After a few failed attempt of searching on google and trying to find a similar sized part in the existing libraries, I decided to design the eagle library myself. Here is the library for download for people out there who might need it:
Here is the carrier board (AKA break out board) circuit diagram and board design in Eagle CAD format:
Hopefully it will be useful for you guys. And btw, I am new to Eagle cad, so the library and pcb design might not be perfect, feel free to improve it.
Here is a link to some very useful Cadsoft Eagle tips and tricks for beginners like me out there:
Here is a link to learn how to design custom parts for Eagle, very nicely written:
