DK-EVAL-04
Description
DK-EVAL-04 is a universal development kit for IQRF
wireless applications with transceiver modules. Very small
size, accumulator and low cost make this kit ideal for use
in network systems.
The user can realize specific functionality by software for
internal TR module.

Hardware
Power supply
DK-EVAL-03 is supplied from accumulator or from external power source
which also serves as a charger. The TR module is supplied when the JP1
jumper is set. Charging is indicated by LED3.
Interface connector
The XC3 female connector for square 0.635 mm, 2.54 mm pitch pins is
intended for I/O and power supply.
Pushbuttons
• User pushbutton SW1
is available on the C5 pin of the TR module. It is active low and weak
pull-up should be provided by the TR module inserted in SIM connector.
Therefore, the TR module should have the C5 pin configured as input
with internal pull-up. It is arranged by OS by default. Wake-up on
change on this pin can also be configured by user software.
• Reset pushbutton SW2
TR module is disconnected from power supply when the SW2
pushbutton is pressed.
LEDs
• LED1 and LED2 are on when the appropriate pushbutton is pressed
• LED3: charging indication. LED3 is on during charging.
Caution: The TR module can be plugged / unplugged into / from the SIM connector while powered off only.
Tip: Use the SW2 pushbutton for this. The TR module is not powered while the SW2 pushbutton is held.
Caution: DK-EVAL-04 layout is optimized for space savings during development of network applications with a lot of nodes
on a table. Thus, this kit is not intended for range tests using TR modules with internal PCB antenna (e.g. TR-52BA, the
range is shortened for ~30% in this case). For range test use external antenna (e.g. TR-52B and AN-03).
