Trackpoint 2 piece
About the Trackpoint 2 piece PCB
Trackpoint 2 piece is an open source PCB design by sadekbaroudi, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 24.8 × 25 mm, with 13 components from 8 distinct parts.
By type, the board carries 5 connectors, 5 resistors, 2 transistors and 1 capacitor.
From the project
This is a VIK module made to connect the trackpoint 2 piece breakout board.
This is a VIK module made to connect the trackpoint 2 piece breakout board.
The through holes should be used if connecting this to a controller that uses 5v logic. The VIK connector is assumed to be connecting to a 3.3v controller, so the logic levels are 3.3v.
The overall design is as follows: VIK uses 3.3V, so the 3.3V through holes all goes to the VIK connector, since VIK expects 3.3V logic. The mosfets (etc) convert the 3.3V logic to 5V logic (and the other way around), so none of the 5V through holes are connected to the VIK connector. The trackpoint expects 5V logic * The 5V logic is…
