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.
Applications
• For TR-52B and highers
• Network development
• Huge IQMESH testing and debug
• Battery powered and portable wireless systems
Key features
• Compatible with IQRF DDC kits (Development Daisy Chain)
• SIM connector for TR module
• 2 pushbuttons, wake-up on button press capability
• 3 indication LEDs
• 6 I/Os
• Accumulator and internal charger
• Charged via microUSB connector
• 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
• Space saving

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. For external power source the micro USB connector XC3 is intended.
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.
Interface connector
Interface connector XC1 makes SIM I/O pins, power supply and ground accessible. It is compatible with IQRF DDC development kits.
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).
