The plastic enclosure base facilitates handling the BL2100 during development, and pro-

protect the components on the other side of the board. The plastic enclosure base is offered
as a separate option when individual BL2100 boards are purchased.
NOTE: Appendix D, "Plastic Enclosure," provides additional information and specifications
for the plastic enclosure.
