I'm planning on making a jig to hold and charge an iPad. Specifically, it will hold it in the landscape orientation, and charge it via the smart connector.
Where can I find the electrical specification for the smart connector?
The specific questions I'm trying to answer are:
What voltage(s) and current(s) do I need to provide? (Secondarily, does it negotiate for higher currents like the USB standard?)
What is the communication interface? As it's only 3 pins total, I'm thinking it's either a bidirectional communication via 1 pin, or it's modulated somehow to reuse pins.
What is the required magnetic setup (polarities, strengths) to align the iPad to the Smart Connector?
