2.2.8 Port-Ext-Board

The Port-Ext-Board (Conrad Order No. 192615) is constructed to expand the functionality of the C-

Control PRO AVR32Bit Mainboard (Conrad Order No. 192702). The product is designed as an open

breadboard experimental circuit board with a pitch of 2.54mm. It is equipped with two single 26-pin

header connectors and suitable only for the port outputs (PORT-1/PORT-2). The board serves to

build your own circuits in conjunction with the C-Control PRO AVR32Bit Mainboard. For circuit

design and the comfortable replica the circuit board is printed with a coordinate system. The board

can directly be mounted under or next to the Mainboard. PCB spacers are needed for "sandwich"

mounting with a minimum of 20mm length and a thread diameter of 3mm.

Connection and Commissioning

Make sure that before you connect the modules to your C-Control PRO AVR32Bit Mainboard all

connections to connected devices are separated and voltage free. On the C-Control PRO AVR32Bit

Mainboard there are two 26-pin header connectors, labeled PORT-1 and PORT-2. This pin header

connectors are suitable for connecting the Port-Extension-Board. On this pins the free ports of C-

Control PRO UNIT AVR32Bit are lead through (see Port-Extension-Board Overview):

Available pins at pin header connector PORT-1:

P5, P6, P7, P8, P9 , P10, P11, P12, P13, P14, P15, P16, P17, P18, P19, P20, P21, P22, P23,

P24, P25, P26, P27, P28, +3.3V, GND

Available pins at pin header connector PORT-2:

P29, P30, P31, P32, P33, P36, P37, P38, P39, P41, P42, P43, P44, P45, P46, P47, P48, P49,

P50, P53, P54, P55, P56, P57, +3.3V, GND

The Port-Extension-Board is connected to the Mainboard via two ribbon cable with pin header con-

nectors (female). Since the cable length may vary according to the application, we offer these com-

ponents for self-assembly using the following order numbers:

Ribbon cable 26-pin RM1.27 0.05mm²: Order No. 607222

Pin header connectors 2x13 RM:2.54mm: Order No. 742185

Tip: The pin header connectors can be easily pressed together with a small vise. Cut the cable

to proper length and straight it in the plug (guide grooves in the plug), and then clamp between the

two vise jaws, and turn it carefully until the connector clicks into place.
