i2c ‘jumper’ cables can be found on the cheap! Just show your local store this:
The shorter the better, so long as extends between your modules, I don’t regret gettin multiple sizes.
The powered bus will be something like the @okyeron’s tt-busboard jr or the hard to find teletype backpack, or even @bpcmusic’s txb…
What are these things? Follow @tehn’s advice and read this AMAZINGLY helpful thread put together by @okyeron :
It can be intimidating at first, but once you start wrapping your head around it, the typical reaction is, “Oh, that’s all this is?”
Plus, since plenty of people have been patient and kind with me on this forum, I’m happy to pay it forward. Feel free to ping me if it still doesn’t click. I’m no expert, but I feel like have the basics down pat.
I ended up going with these 3 pin jumper wires https://www.sparkfun.com/products/10368 because I didn’t want to deal with worrying about using electrical tape or heat shrink tubing to keep 3 separate wires together. It’s not labeled as such, but when you order a premade i2c cable this is what you’re getting.
@dansimco the only thing I will add is to make sure the wire lengths are long enough. I’ve been trying to sort out my 16n Faderbank i2c control of my ER301 and, because of the position of the i2c jack on the faderbank and distance from the back of the 301, its definitely not a stable connection. I even found that when I had teletype, Just Friends, and Ansible with a teletype backpack, it was a stretch to get the i2c cable i had on hand to where they needed to be…i still havent gotten i2c to work at all, but everytime someone mentions it they talk about how its fiddly and the shorter the wires are the better, but I’m not sure where the tipping point is…
Anyone have a guideline for the length range our i2c cables should try to fall into?
