Using an Arduino Micro as a USB adapter for ThinkPad T60 keyboard with TrackPoint support. Supports different keyboards from the ThinkPad family that shares the same receptacle as T60.

Introduction

Using an Arduino Micro as a USB adapter for ThinkPad T60 keyboard with TrackPoint support. Supports different keyboards from the ThinkPad family that shares the same receptacle as T60.

Photo: Modular approach that splits the circuit into the microcontroller side and receptacle + supporting ICs side.

Plans for PCB

Hi,

Can I please have the plans for the PCB? I am trying to build it and would be super stoked if you could provide the PCB plans.

JAE AA01B-S040VA1 EAGLE library

Hi @rampadc ,

First of all I appologize for opening this here, (since it is not related to the SW).

Could you please share with me the Lenovo connector EAGLE library?
If you can share any of the PCBs that would be fine as well.

Thanks in advance!

Document keyboard connector/receptical type and manufacturer

The physical interface is a 40-pin board-to-board connector. Ideally the type and source of this connector would be documented in the source code and documentation.

The page at:

• https://hackaday.com/2014/04/30/using-a-thinkpad-keyboard-over-usb/

states:

"The connector is an extremely odd proprietary deal, that can be found through the usual channels for about $5 in quantity 100."

Another source suggestions that the connector is not proprietary, but just out of production was only generally produced in large batches for IBM/Lenovo.
