KiCad PMOD compatible connector Library

KiCad Library to make it easy to create both host boards and expansion boards and which are compatible with the Digilent "PMOD" specification.

Library has;

• Schematic components for "Host Side" and "Device Side" for the following PMOD types;

• Type 1 - GPIO (plus what I call Type 1A which is a "dual" Type 1 connector).

• Type 2 - SPI

• Type 2A - Expanded SPI

• Type 3 - Old style UART

• Type 4 - New style UART

• Type 4A - Expanded new style UART

• (TODO) Type 5 - H-Bridge

• (TODO) Type 6 - Dual H-Bridge

• (TODO) PCB module footprints.

• (TODO) KiCad templates

PMOD

Pmod interface or Peripheral Module interface is a standard defined by Digilent Inc in the Digilent Pmod™ Interface Specification for peripherals used with FPGAs or micro-controllers.

A lot of Pmod information is collected in the following Google Spreadsheet

The PMOD header is found on a wide variety of FPGA boards including many not developed by Digilent,

• Atlys a Xilinx Spartan 6, video testing platform. The board only has 1 "dual" PMOD header by default but can have another 4 dual added by the vmod-mib expansion board.

• Zybo, A low cost Xilinx Zynq development board. The board has 5 dual PMOD headers and one dual Analog PMOD header.

• Zedboard, A higher end, very popular Xilinx Zynq development board. The board has 5 dual PMOD headers.

• Mimas V2 A budget Spartan 6 board with plenty of power. The board has 5 dual PMOD headers.

• Arty A7 An affordable Xilinx Artix-7 development board. The board has 4 dual PMOD headers.

Example Pmod expansion boards can be purchased from;

• Digilent at http://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,401&Cat=9
• Numato at http://numato.com/fpga-boards/expansion-modules.html
• Zedboard at http://zedboard.org/accessories/pmod
• Maxim at http://www.maximintegrated.com/en/design/design-technology/fpga-design-resources/pmod-compatible-plug-in-peripheral-modules.html

PMOD "Extensions"

There are a number of unofficial extensions to the PMOD standard. These include;

• Using multiple PMOD headers which are next to each other.
• An "Analog PMOD header" found on the Zybo.
• An "High speed PMOD header" found on the Zybo.
