Hardware
Power supply
DDC-SE-01 should be supplied from DK-EVAL-04 via connector XC2.
Interface connectors
The XC2 male connector with square 0.635 mm, 2.54 mm pitch pins
is intended for I/Os and power supply.
Corresponding XC1 female connector serves for interconnection with
other DDC kits.
XC3 is a 1.25 mm pitch miniature connector DF13C-5P (Hirose).
Mating Hirose cable connector: DF13-5S (plastic shell), DF13 crimp
contacts.
Internal peripherals
•
I
2
C temperature sensor:
MCP9802A3 (Microchip) with fixed I
2
C
slave address 10010110 (in binary).
•
1-wire temperature sensor:
DS1820B20 (Dallas).
•
Photoresistor:
PGM5539 by Token. Resistance 30-90 kΩ at 10
lux, dark resistance 5 MΩ.
•
Potentiometer:
The potentiometer is intended for voltage
measurement using the A/D converter inside the MCU on the TR
transceiver.
Caution
To enable correct functionality of the pushbutton SW1 on the DK-EVAL-04(A) kit connected, the potentiometer shaft
must be in the intermediate position.
