This long range radio TinyShield is based around the very popular Silicon Labs SI4432 radio transceiver - the same transceiver as used by the HopeRF RFM22B module. The TinyShield is set to operate at 433MHz and can transmit at up to +20dBm and is very easy to use. This transceiver allows for long range communication between radios and is designed for an open field range of up to 500 meters, which makes this great for long range sensors of RC control (like drones and vehicles).
An U.FL antenna connection is included on the board, along with a 433MHz whip antenna. The TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
