IR

An elementary IR receiver driver class for TSOP4838 (InputPin).

NEXA

NEXA Wireless (RF433) Lighting Control receiver and transmitter (ExternalInterruptPin/OutputPin).

NRF24L01P

Driver for the nRF24L01 Single Chip 2.4GHz Transceiver (SPI).

RFM69

Driver for the RFM69W/HW ISM Transceiver Modules (SPI).

VWI

VWI (Virtual Wire Interface) provides features to send short messages, without addressing, retransmit or acknowledgment, a bit like UDP over wireless, using ASK (Amplitude Shift Keying). Supports a number of inexpensive radio transmitters and receivers (RF315/433), and may be configured to use different codecs; VirtualWireCodec, ManchesterCodec, Block4B5BCodec, and BitstuffingCodec (InputPin/Timer).
