Anything like the Logitech K400 Keyboard but that is open sourced and wired?

Is there a keyboard similar to the Logitech K400 keyboard but with the following changes...

• Open source firmware
• Open source hardware (would be nice)
• Wired (Could be wireless if wireless connection is end-to-end encrypted)

Would like it to have...

• Touchpad
• Thin/portable (besides not being wireless)
