This ATTiny24-based 433MHz platform is a remote sensor base. Add up to 4 sensors (analog or digital), and configure the board's broadcast schedule!
This receiver type is good for data rates up to 2400bps and will only work with the 315MHz transmitter.
This is only the 315MHz transmitter. This will work with the RF Links at 315MHz at either baud rate. Only one 315MHz transmitter will work within the same location.
