LIO Monitor

The Chipmunk LIO Monitor is a small tool that makes the life of the repair technician a little bit easier.

This board plugs into the LIO connector of the motherboard of a MacBook air. The LIO cable can (if you want) plug into the top of the card again to reconnect the LIO board. Effectively the LIO Monitor sits between the motherboard and the LIO cable. With six LEDs it shows six signals that are available on the LIO connector. .

There are two versions available. One for the 11 inch models of the MacBook Air, and one for the 13 inch model. Electronically the boards are the same. The physical shape however is different to fit in the respective machine.

13 Inch version for boards: 820-3209, 820-3437

11 Inch version for boards: 820-3208, 820-3435 (not available)


You can order now and pay by PayPal.

The Chipmunk LIO Monitor costs 80 EURO including shipping world wide.
