Custom Products

In addition to the standard components needed for constructing the PDT the following custom printed circuit boards (PCBs) are available for purchase. The PCBs are not required but they simplify the construction of the PDT by providing mounting and wiring points for the various components.

PDT shield PCB

The main PDT PCB has the standard Arduino shield format that allows it to be stacked directly on top of the Arduino Uno microcontroller. A bare PCB and one populated with components are shown below.
