DK-EVAL-03
Description
DK-EVAL-03 is a universal development kit for IQRF wireless applications with transceiver modules TR-52B. 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
• Network development
• Huge IQMESH testing and debug
• Battery powered and portable wireless systems
Key features
• SIM connector for TR module
• 1 pushbutton (with wake-up on change capability)
• Up to 3 I/Os available on USB connector
• I 2 C interface via USB connector
• Voltage output to supply low power peripherals,
sensors etc.
• Accumulator and internal charger
• Charged via microUSB connector
• Optional DK-PWR-01 power supply board supports
operation and charging up to 5 kits
• Charge status LED indication
• Space saving, low cost

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 LED1,
(LED is switched off when fully charged). Do not connect DK-EVAL-03 to PC USB port.
Voltage output
Voltage output is inteded to supply low power peripherals, sensors etc. via the USB connector, pin 4. It is provided by the TR module inserted in
SIM connector via the C2 pin. Therefore, the TR module should have the LDO output enabled
(recommended, default disabled) or the C2 pin configured as output and driven high (which allows significantly lower voltage and load).
Digital I/Os
Two digital lines are connected between the TR module (pins C6 and C7) and the USB connector (pins 3 and 2). They can be used for I 2 C communication or as general purpose I/Os.
If the voltage output is not used the C2 pin can also be used as digital output. Note that this output can be driven high only due to the D1 protective diode.
Pushbutton
User pushbutton S1 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.
