This long range radio shield is based around the very popular Silicon Labs SI4432 Radio Transceiver - the same radio as used by the HopeRF RFM22 module. Although this TinyShield is still in beta, we are designing for an RF range of over 500 meters, making this great for long range sensors or RC control (like drones and copters). Coupled with TinyScreen, this makes for a great way to display data from remote sensors, display data back from your robots, and create all sorts of cool remote display projects.
