I'm a happy owner of an Axon 2 for the last week, I have already tried some sensors and everything works good.
I have the TPA81 thermal array sensor from Devantech, an amazing little sensor that can even produce a thermal image of an
environment with the apropriate software.
However, it uses I2C and I need 4 pins for that ( 5V, GND, CLOCK and DATA).
Instead, the I2C pins in Axon 2 are only three.
I know it may sound stupid, but how can I actually plug it on Axon 2 ?
In my other microcontrollers ( Brainstem and Wiring ) I have succesfully used it.
