The RE-Mote features an optional custom-made enclosure to fit most scenarios, allowing to easily connect sensors, actuators and rechargeable LiPo batteries. Its on-board RP-SMA antenna eliminates the need to mechanize an external antenna, allowing to alternatively use either a sub-1GHz or 2.4GHz antenna, or a multiband one.
