i2c set up

in order for white whale/meadowphysics/earthsea/ansible to be able to control er-301/just friends/telexo via i2c you will need to use a powered i2c board as these modules weren't meant to work as i2c leaders originally.

you can use one of the following:

make sure to mount the board so that there is no chance that something might accidentally touch any of the exposed pins!!

monome and bpcmusic offered assembled boards before but they are sold out. at this point the only other option i'm aware of is the upcoming TELEXb module: https://store.bpcmusic.com/products/telexb

it's also possible to DIY one yourself. detailed instructions are available here: https://github.com/monome/tt-busboard
jimi23 also designed a version of the backpack for ansible, instructions/files are here: https://github.com/james-everitt/ansible-i2c-busboard

simply connect all your i2c enabled modules to the i2c board - make sure that GND is connected to GND, SCL to SCL and SDA to SDA. you can use either a single set of 3 pins or if you have a double set you can use either side or both.
