OpenTracker1+ SMT
OpenTracker1+ SMT Schematic

Assembled and tested OpenTracker+ surface-mount (SMT) board. This version of the OT1+ is perfect for installation inside a radio or any other application where size and weight are a concern. Without pins installed, the board measures 1.22 x 0.72 x 0.2" (31x18x5 mm).

All off-board connections are through a double row of holes, in a standard 24-pin DIP footprint. Two pin header strips are provided (not installed) to allow the board to be mated with another PCB or installed in a solderless breadboard.

This board does not include a built-in temperature sensor or LEDs.
