DDC-SE-01
Description
A sensor development kit for IQRF wireless applications
with transceiver modules (TR) plugged in DK-EVAL-04
kit. Compatible with other DDC (Development Daisy
Chain) kits.
Ready-to-use examples are available demonstrating how
to use I2C and Dallas 1-wire buses and A/D converter
inside TR to measure temperature, voltage etc.

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.
Jumper JP1

•
In position 1 – 2 enables 1-wire sensor.
In position 2 – 3 enables I2C temperature sensor and I2C
external bus.
Sensors
I2C temperature sensor: MCP9802A3 (Microchip) with fixed I 2C
slave address 10010110 (in binary).
• External I2C device must have I2C slave address different from
10010110 (in binary).
• 1-wire temperature sensor: DS1820B20 (Dallas).
• Photoresistor: A906013 by Perkin Elmer. Resistance 8 kΩ at 100 lux, dark resistance ~1.5 MΩ.
•
Refer to datasheets of used devices.
