All the parts I ordered for the motorized slider are coming in slowly. The motors from All Electronics are really nice. One annoying quirk about the stepper motor is the 2 mm female connector. Why it couldn't have been 2.54 mm, I'm not sure. In the end, I just bent a set of standard headers into the correct width. Interestingly, the gear motor had a 2 mm male header with far more pins than was needed for the encoder and motor power. On the back of the header was a 8 pin SOIC chip. Upon closer inspection, I found out that it was an I2C EEPROM (
M24C02). I hooked up (poorly soldered) wires to read the EEPROM but found that it was empty (the entire thing was filled with 255 and 254). I wrote some data to it to verify that it was functional, and I was able to read my data back. I'll have to find a use for it later.
