Some samples I have got:
I got a STN1110 chip rather quickly after asking for it. Here is a bit of info that I quoted from a thread where I got the info.
STN1110 ICs from here: http://www.obdsol.com/stn1110/
The STN1110 chip supports all the OBD-II protocols. If you want something a little more user-friendly (and a little more expensive) you can also get the ODB-II UART board from Sparkfun (http://www.sparkfun.com/products/9555
) which also uses the STN1110.
Or you could build your own version of the Sparkfun board using their schematics.
I got an STM32F4 discovery board from ST, www.st.com
for free which was nice. I struggle with using it but, it is a nice board!
Most recently, I got 4 chips from Atmel by filling out their form for receiving samples. I have a thread about that here in bar sport.
In each case, I answered honestly, and had no problems getting the chips.
Anyone else have any luck getting samples?
