I2C Encoder

We are currently working on the second version of this board.

Here there are more details: https://hackaday.io/project/122039-i2c-encoder-v2

First of all this product is on sale on Tindie !

Second, i made a new HW release with the I2C pull-up issue resolved. 

For resolving the problem i just split the P-UP jumper in two.
I already update the documentation on GitHub.

I also made a very useful bed of nails for programming and testing the boards.

For the testing purpose i used an Arduino board that simulate the encoder rotation, the address jumpers and check the LED voltage.

Thanks to the community i found a problem on the i2c pull-up resistor.
When the P-UP jumper is open, the two resistors are in parallel to the SCL and SDA pins, which causes problem on the bus. 
The solution is simply remove them when pull-up resistors are not used.

My appreciations to the hackaday community!

I created a GitHub repository, here you can find all the documentation about the project.

I'm selling this board on Tindie, everyone around the world is welcomed to buy it !
