===== Features =====
  * 6 external test point headers
  * Easily access and test signals passing through
  * 6-pin Pmod port with %%GPIO%% interface

----
=====Functional Description =====
The %%PmodTPH%% is a great way for users to get easy access to signals coming in and out of the system board by acting as an intermediate between the system board and the peripheral component.

----
===== Interfacing with the Pmod=====
The %%PmodTPH%% is a pass through module, making it essentially equivalent to a set of six wires coming from the system board with center taps that users can attach their multimeter probes to. Consequently, there is no particular protocol that is associated directly with this Pmod.  {{ :pmod:pmod:tph:temp2.png?200|PmodTPH Block Diagram}}

==== Pinout Description Table ====
^  Pin  ^  Signal  ^  Description             ^
|  1    |  P1    |  Signal 1     |
|  2    |  P2    |  Signal 2     |
|  3    |  P3    |  Signal 3     |
|  4    |  P4    |  Signal 4     |
|  5    |  GND   |  Power Supply Ground  |
|  6    |  VCC   |  Positive Power Supply  |

As there are no integrated circuits on this Pmod, any external power that is usable with the system board can be applied to the %%PmodTPH%%.

----
===== Physical Dimensions =====
The pins on the pin header are spaced 100 mil apart. The PCB is 1 inch long on the sides parallel to the pins on the pin header and 0.8 inches long on the sides perpendicular to the pin header.

----
===== Additional Information =====
The schematics of the %%Pmod TPH%% are available {{reference:pmod:pmodtph:pmodtph_sch.pdf|here}}. 

As the Pmod TPH is a just a pass through module with additional contact points to monitor the signals and does not modify the signals in any way, there is no appropriate code to demonstrate how to use the the Pmod TPH.
