All Model F Labs keyboards are wired, so you need a proper USB hub/adapter/docking station. I tried my Ultra Compact F77 with my iPhone (don’t have an iPad) via the USB camera adapter kit and got an error saying “this accessory requires too much power” so I guess probably “regular” iPads won’t work either. However, an iPad Pro (with USB-C) and a proper powered docking station may be able to supply enough power. The ibm-capsense-usb controller speaks standard HID protocol, so there shouldn’t be any problem as long as you can supply enough power to this keyboard.
