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.
X1 and X2 clamp connectors to connect contacts of relays.
Control circuitry
To simplify wireless control of relays and reduce power consumption,
the kit is equipped with MCU and control circuitry. Thus, relays are
driven according to the level of control pins (C8 for RE1 and C2 for
RE2). Normally open contact is open when the control pin is set to low
level.
Relays
FTR-B3GB003Z miniature 2-contact bistable (latching) signal relays by
Fujitsu are used. For higher contact rating both contacts are connected
in parallel.
Refer to datasheets of the relay.
Software
Ready-to-use examples are available in Startup package at www.iqrf.org.
