It would be great to get the Android app source for this

You should actually be able to get 4096 discrete positions out of this encoder as the count is usually the number of lines and you get 4 edges per line. NB not tested with this encoder.

The Eagle files are not Eagle files, just Gerbers and Drills

Looks like this would give you the data you want, but not via the serial port, looks like it decodes the screen data.

Hi
If you plug the motor directly into the rated voltage it will draw the rated current.
Normally it is recommended to run them at 5-20 times the rated voltage and use a chopping stepper motor driver, like the easy and bigeasy drivers or a L297/L298 combo, to control the current.
If you hook it up to an L298 at 4.5V but don’t control the current you will draw more than the rated current and overheat the motor or L298.
If steppers are run at higher than rated current or higher than about 20x rated voltage they can overheat and start to de-magnetise and lose torque.
Also note that at rated current you can easily get a 60 or 80 deg (Kelvin) rise above ambient on motors like this, which is pretty normal.

The data sheet also specs the max VCC and GND currents as 70mA, which means either the chip will possibly burn out or the brightness will possibly vary as you increase the number of non-current-limited lit LEDs.
Also note there is a max power dissipation for the SO16 package of 500mW which, if I’m interpreting things correctly, would mean that you can only have 12.5mA per channel if all channels are permanently lit.
Please correct me if I’m wrong.

I would love to see a footprint on the next revision of this board for a MAC address EEPROM so that you don’t have to make one up. Something like this would be ideal, only takes one IO and it wouldn’t have to be populated, the user could add it if they wanted.

Heres an arduino code snippet for quadrature encoders
Product COM-10790 | about 9 months ago
If you read the data sheet you will see that the E6A2-CS3E model is a “singleness output ‘A’” [sic] type.
This means that it is neither a quadrature nor gray code encoder (which are not the same thing btw) and you cannot determine direction, only speed, and position in one direction, with one signal.
Also backing this up the datasheet says “The white (green) and orange (yellow) lines of the single type (E6A2-CS) do not output signals (no connection)”.
You would need the E6A2-CW3E for a quadrature output and E6A2-CWZ3E for quadrature with Z (origin) signal.
