4. Using the 433 MHz radio modules
4.1 Connecng the modules
You can also connect sender and receivers of 433 MHz radio modules to the Talking-Pi board to control
radio devices.
Just plug the modules into the marked connecons (433 TXD: 3-Pin Sender, 433 RXD: 4-Pin Receiver).
The modules should (note the marked arrows) direct away from each other.
Warning! Please note that you can not use the Driver1 and Driver2 connecons and the 433MHz
modules at the same me.
The sender is connected to the GPIO port 17 and the receiver to the GPIO port 27.
Normally no addional conguraon is needed here.
