My students often blame the photon when their software does not work, which is silly since there are so many other things that might be wrong, however after teaching 3 semesters using the Photon it is possible that the occasional photon pin might be messed up. Has anyone made a photon test PCB and if so would you share the Eagle schematics? I assume particle.io has something for testing Photons.
I am thinking about making a testing board. The digital and analog input and output pins would be easy to test with photoresistors and LED’s but how could I test uART, SPI and I2C pins without actually connecting expensive other boards. Are there test chips for each form of serial communication?
here is a link to a cheap I2C chip
Just remembered I have 10 of these that I can use.
