GW-QVGA-01A is a programmable control panel with QVGA
display / touchscreen adaptable to user specific functionality.
It can also be used as a user programmable gateway for an
interface between a human operator and an IQRF wireless
GW-QVGA-01A is a generic equipment, i.e. the hardware is
fixed and the user can realize specific functionality by
software only. It is intended for final production while
applications should be developed using the DS-QVGA-01
development set.

Power supply
GW-QVGA-01A is intended to be supplied from external stabilized 7 V – 24 V DC connected to clamp or 5V DC to
micro USB connector. Accumulator serves as a backup for external power source and should be charged from it. Use
only the proper power source and keep proper polarity according to the PCB print for the clamp connector.
GW reset (initialization / starting-up) can be invoked by the pushbutton on the side of the case. Use this pushbutton
to switch the GW on.
Sleep mode
This standby mode is intended for current consumption minimizing, especially in idle or while supplied from the
accumulator. It can be invoked by the program and terminated by the reset pushbutton. GW power is not switched
off, the Sleep mode is used instead.
QVGA display
Display / touchscreen 3.2“ diagonal, 320x240 pixels RGB, 262144 colors (graphic library uses 65535 colors only),
QVGA TFT LCD, transmissive, with LED backlight and 16b data bus.
Used type: DI-QVGA-3.2-03 in GW-QVGA-01A(1) version.
Proper display functionality requires a calibration (setting the touch sensors in accordance to display pixels) to
compensate variations in parameters due to temperature, tolerance of parts and so on. The GW has the display
factory calibrated and this can also be done in application software whenever needed (3x3 touches in places
indicated by an arrow). The calibration is stored to the EEPROM.
LED backlight can be switched on / off by the application software.
EEPROM memory
64 kb, serial interface SPI, 1 000 000 erase / write cycles (typ.).
RAM memory (optional)
64 kb, serial interface SPI.
RS-485 interface
The RS-485 circuitry is supplied directly from external source. Thus, it works with external supply only.
TR module and antenna
The TR-52BA or higher wireless IQRF transceiver module in SIM card format with integrated PCB antenna can be
User pushbutton
Functionality of the pushbutton on the front panel is fully depended on the user application.
External power
TR module
Micro USB
Clamp connector
