Depends on wether you want to be able to adjust pfd. The board has provisions to satisfy pfd as a fixed value via two fixed 4.7K resistors, or vary pfd with a 10K trim pot. http://www.allegromicro.com/datafile/3977.pdf is the datasheet that explains pfd. Easiest and cheapest is to use the two 4.7K resistors.
