Description
RC-04 is a uni ersal user programmable IQRF remote
controller with bidirectional communication.
It is a generic equipment, i.e. the hardware is fixed and the
user can realize specific functionality by software for internal
microcontroller. This can be uploaded by the user ia RF
(which is the only way how to upload the code into the
de ice).
Applications
• Portable controller
• Automation
• Voting systems
• Wide usage facilities
Key features
• Built-in IQRF transcei er module
• Programmable ia RF only
• Architecture based on TR-52, FSK
• On-board PCB antenna
• 4 pushbuttons, 2 LEDs
• Bidirectional communication – high security in comparison
to unidirectional systems
• High performance
• Sleep mode with ultra low power consumption
• Coin battery
• Low cost
Simplified schematics

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.
Supply oltage (VCC): 3.5 V
Storage temperature: -40 °C to +85 °C
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.

RC-04
Software
Demo application
This demo illustrates unidirectional non-networking communication between the RC-04 controller and the CK-USB-04
kit equipped with the TR-52B module connected to PC with the IQRF IDE Terminal running. The RC04_simple.c
program is intended for the controller and the E02-RX (one of basic IQRF examples) for the TR module in the CK kit.
Both are a ailable on IQRF CD and IQRF website. To upload the RC04_simple.hex to the RC-04 ia RF – see
Application note AN009 – IQRF wireless upload. Switching to RF PGM mode after reset is enabled by default.
In idle state the controller stays in Sleep mode allowing wake-up by any pushbutton. After wake-up the battery
oltage is checked and LEDs flashing indicates pressing the button and accumulator condition. Then respecti e
command is sent to CK-USB-04 and the controller gets to sleep again.
Buttons Function
•S1 text sent: "S1x" x=0 if battery O.K. otherwise x=1
•S2 text sent: "S2x" -"-
•S3 text sent: "S3x" -"-
•S4 text sent: "S4x" -"-
•S3 + S4 for more than 5 s enter RF PGM mode
•S2 for more than 0.7 s lea e RF PGM mode
LED indication
•button S1 to S4 1 x flash green (battery O.K.) / red (battery exhausted).
•RF PGM indication See the Application note AN009 – IQRF wireless upload.
Caution: Select the proper ersion of Demo according to IQRF OS ersion (2.11 or 3.xx) implemented in RC-04.
To distinguish OS ersion, catch Module Info which is always sent by this Demo application just before switching to
RF PGM mode in IQRF IDE Terminal. Show hexa checkbox should be checked. OS ersion is in buffer
moduleINFO[4]. See the picture abo e and IQRF OS User's guide.
Example:
moduleINFO[0–7]
[0] [1] [2] [3] [4] [5] [6] [7]
3C 5D 00 01 30 03 39 11
moduleINFO[4] = 30 means OS 3.00
moduleINFO[4] = 2B means OS 2.11

RC-04
Caution!
The only way how to upload user application into the RC-04 is RF PGM (wireless programming, ICWP). Demo
application RC04_simple.c in okes the enableRFPGM function first. It ensures that after e ery reset (due to
reconnecting the battery) the de ice is switched to RF PGM mode and can possibly be reprogrammed. This feature
can be remo ed (by disableRFPGM), but it should not be done unless there is another reliable way how to in oke
back the RF PGM mode using runRFPGM after pressing a pushbutton. See the demo application, refer to AN009
Application note for details. If bein omitted the device can not be repro rammed any more. Reco ery is
possible by the manufacturer only.
Tip: Always use enableRFPGM during de elopment.
