Description
DK EVAL 04A is a universal development kit for wireless
applications with IQRF transceivers. Very small size, LiPol
accumulator and low cost make this kit ideal for use in
networks.
A user specific functionality is given by application
software in internal TR transceiver.
Applications
• Development of wireless applications
• Host for IQRF TR transceiver
• Debug and testing of huge IQMESH networks
• Battery powered and portable wireless systems
Key features
• SIM connector with plastic holder for TR transceiver
• 2 pushbuttons, wake up on button press capability
• 3 indication LEDs
• 6 I/Os
• LiPol accumulator and internal charger. Charged via
micro USB connector
• Accumulator over current and over discharge protection
• Voltage output to supply low power peripherals,
sensors etc.
• Optional DK PWR 01 power supply board to support
operation and charging up to 5 kits available
• Compatible with IQRF DDC kits (Development Daisy Chain)
• Space saving

Hardware
Power supply
DK EVAL 04A is supplied from the internal accumulator or from external power source via micro USB connector XC3 which
also serves as a charger. The TR transceiver is supplied when jumper JP1 is set. Charging is indicated by LED3. The
accumulator is protected against over current (by resettable fuse SN035 16) and against over discharging.
The accumulator should be kept charged.
For external power source also connector XC1 (pins 6 and 7) can be used.
Jumper JP1 must be disconnected in this case.
Pushbuttons
•User pushbutton SW1
is connected to pin C5 of the TR module, active low. Therefore, the TR module should have the C5 pin configured as an
input with internal pull up. It is arranged by OS by default. Wake up on change or interrupt on change on this pin can
also be configured by user software.
•Reset pushbutton SW2
TR module is disconnected from the 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 and switched off when fully charged.
SIM connector
Caution: The TR module can be plugged / unplugged into / from the SIM connector while powered off only.
Tip: Use the S 2 pushbutton for this. The TR module is disconnected from power while the S 2 pushbutton is held.

Caution: The unsupported TR modules must not be plugged into DK-EVAL-04A SIM connector.
Interface connector
Interface connector XC1 makes SIM I/O pins, power supply and ground accessible externally. It is compatible with IQRF
DDC development kits.
Range test
Caution: DK-EVAL-04A PCB layout is optimized for space savings during the 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-
72DA, the range would be shortened in this case). For range test, use either e.g. TR-72DA with range extender RNG-EXT-
01 or TR-72D with an external antenna.
Software
For application software refer to examples in IQRF Startup package.
For power consumption measurements, no TR pins must be left as digital inputs without defined input log. level values. See
example E14 CONSUMPTION.
