RC-03
Description
RC-03 is a universal user programmable IQRF remote
controller with bidirectional communication and accumulator.
It is a generic equipment, i.e. the hardware is fixed and the
user can realize specific functionality by software for internal
TR module only.
Applications
Key features
• Portable controllers
• Internal TR-52B transceiver module

Hardware
RC-03 is a generic equipment, i.e. the hardware is fixed and the user can realize specific functionality by software for
internal TR module only.
Power supply
RC-03 is supplied from the accumulator and charged via microUSB connector. Mains adapter is intended for it.
Supplying from PC via USB is not allowed.
Sleep mode
It is possible to switch off all functions and peripherals to minimize supply current. For Sleep mode control refer to
demo software included. The power can not be switched off at all, the Sleep mode is used instead of this. The
controller wakes-up automatically after any pushbutton press (if enabled by SW).
Pushbuttons and LED
Functionality of all three pushbuttons and the LED is fully under user software control.
TR module
Wireless IQRF transceiver module TR-52B in SIM card format. Higher types are also supported. User program
should be uploaded by an external programmer outside the GW.
Inputs/outputs
Two TR pins (C6 and C7) are connected to the USB connector for general purpose usage.
Antenna
Built-in PCB antenna on the RC-03 board.
Caution: To enable TR removal, the GW is delivered with TR module not connected to the antenna. It should be
soldered by the user before final usage.
Case
The plastic case is limited to a very few number of open/close cycles only. Development should be accomplished with
opened case.
Software
Demo application
This
demo
illustrates
unidirectional
non-networking
communication between the RC-03 controller and the CKUSB-02 kit equipped with the TR-52B module connected to
PC with the IQRF IDE Terminal running. The
RC03_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 available on IQRF CD and IQRF
website.
In idle state the controller stays in Sleep mode allowing wakeup by any pushbutton. After wake-up the battery voltage is
checked and LEDs flashing indicates pressing the button and
accumulator condition. Then respective command is sent to
CK-USB-02 and the controller gets to sleep again.
