Hello on the forum,
I would like to add a sensor package to my BR2 that monitors the hydraulics for a manipulator arm I’m trying to build. It has a small controller that reads various inputs, and displays them on a small OLED display. The problem is the display is driven by I2C. I’d like to send the I2C data up a spare tether pair so I can connect the display at the surface. I’ve scoured the Internet, and failed to come up with a solution for a tether length of 100m or more. I’ll be using two arduinos (Master-Slave/RS485) to control the thing, I’m wondering if there is a way to leverage them?
