1.2 Physical Dimensions
The pins on the pin header are spaced 100 mil apart. The PCB is 3.45 inches long on the sides parallel to the pins on
the pin header and 2.00 inches long on the sides perpendicular to the pin header.
2 Functional Description
The Pmod MTDS has an on-board PIC32MZ microncontroller that is running the MTDS firmware. To communicate
with the device, you must use the MTDS and MyDisp libraries available and documented on the MTDS resource
center. Arduino and chipKIT host boards should use the Arduino IDE libraries, and Xilinx FPGA or Zynq based host
