Absolute maximum ratings
Stresses abo e those alues may cause permanent damage to the de ice. Exposure to maximum rating conditions
for extended periods may affect de ice reliability.

Hardware
RC-04 is a generic equipment, i.e. the hardware is fixed and the user can realize specific functionality by software for
integrated transcei er module only.
Power supply
RC-04 is supplied from the coin non-rechargable battery.
Sleep mode
It is possible to switch off all functions and peripherals to minimize current. For Sleep mode control refer to demo
software included. The power can not be switched off at all (unless remo ing the battery), the Sleep mode is used
instead of this.
Tip: User SW should allow wake-up the controller after pushbutton(s) press. See demo SW included.
Pushbuttons and LEDs
Functionality of all four pushbuttons and both LEDs is fully under user software control.
RF transceiver
Integrated IQRF wireless transcei er based on the TR-5xB architecture. User SW uploading is possible ia IQRF
wireless upload only (without opening the case).
Antenna
Built-in PCB antenna on the RC-04 board.
