We are manufacturing, exporting Base Boards that may be used for a number of pluggable headers (PH Boards). Here, these are used as a general purpose peripheral board and are suitable for use with assorted Cortex based microcontrollers. If required, you can use it with other controllers whose pinout configuration is same as that of the flyer. Using these base boards it is also possible to keep the same peripheral connectivity. For number of pins and their width, check the technical specifications of each product.
