Important Warning!!!

The radio modules on all 100mW models are not 5 volt tolerant. If you connect 5 volt power to the programming
headers, you may damage the radio module.
**Only connect a programming cable that provides 3.3 volt power.**
Fortunately, the other components on the receivers and transmitters are tolerant of 5 volts, and the radio
module is replaceable if you damage it.
