For the BMD-301, refer to the external antenna datasheet for antenna placement and grounding
recommendations.
11.2 Mechanical Enclosure
For the BMD-300, care should be taken when designing and placing the module into an enclosure. Metal
should be kept clear from the antenna area, both above and below. Any metal around the module can
negatively impact RF performance.
The module is designed and tuned for the antenna and RF components to be in free air. Any potting, epoxy fill,
plastic over-molding, or conformal coating can negatively impact RF performance and must be evaluated by
the customer.
For the BMD-301, refer to the external antenna datasheet for placement in or on a mechanical enclosure.

12. Evaluation Boards
Rigado has developed full featured evaluation boards that provide a complete I/O pin out to headers, on-
board programming and debug, 32.768 kHz crystal, power & virtual COM port over USB, 4 user LEDs, and 4
user buttons. The evaluation boards also provide the option to be powered from a CR2032 coin cell battery,
and have current sense resistors and headers to allow for convenient current measurements. An Arduino Uno
R3 style header is provided for easy prototyping of additional functions. The evaluation boards also support
programming off-board BMD-300 modules.
