What cord do you use to connect to an iPad?

Hi cinnamon-bun! When I saw your model, it was connected to an iPad. However, the supplies list has a usb-c to usb cord. The waffleboard is the side with the usb-c connection, correct? Then is the usb side connected to a usb hub which is then connected to both power and iPad-via-lightning-port?

Or do you use a usb-c to lightning cord? Did you experience power draw issues?

Thanks!!

The waffletone has a USB-C port because it uses a Elite-C microcontroller instead of a Pro Micro usually seen on DIY keyboards, which are microUSB.

To connect to a computer the other end of the cable needs to be USB-C or USB-A depending on the computer.

To connect to an iOS device via Lightning, you need an official Apple adaptor. There are two: one with no power and one with an extra lightning socket for power.

iOS devices are physically capable of powering Waffletones (which are low power devices) but the Waffletone has to advertise itself with a low power draw number when plugged in. The README has instructions on how to set up the firmware properly. This allows you to use an iOS device on its own battery power.

If you don't do that, you have to use the powered version of the lightning-USB adapter. You could in turn power that from a USB battery pack, or plug it into the wall.

New iPads are starting to use USB-C and I don't know if that will just work with a plain USB-C to USB-C cable or if you need an adapter. It depends on whether the iPad acts as a USB host or a USB child device.
