101 C-Control Pro IDE

2.2.6 UNIT-BUS Exp. Board

The C-Control PRO AVR32Bit UNIT BUS Exp. Board (Conrad Order No.: 192659) is designed to ex-

pand the functionality of the C-Control PRO AVR32Bit products. The product is designed as an open

circuit board with six single 6-pin pin header sockets, and only determined for the UNIT-BUS of the

C-Control PRO AVR32Bit and the C-Control I product family (extensions) and their sockets. The

control of the individual modules is done via software. The software can be found in the folder of the

example programs (see demo programs) and at www.c-control.de.

Connection and commissioning

Make sure that before you connect the modules to your C-Control PRO AVR32Bit base product (e.g.

AVR32Bit Application Board - Order No. 192587 or Mainboard - Order No. 192702) all connections to

connected devices are separated and voltage free. On the C-Control PRO AVR32Bit basic products

there is also a 6-pin connector labeled UNIT-BUS. This pin header connector is suitable for connect-

ing UNIT-BUS expansion modules. Each of these jacks includes the lines SDA, SCL, RxD,

TxD, +5V and GND. The C-Control PRO AVR32Bit Unit works with 3.3V level, and the UNIT-BUS ex-

tensions, as well as the older C-Control I2C-bus modules, use 5V. Therefore a level converter is

placed between the C-Control PRO AVR32Bit UNIT and the UNIT-BUS that converts the 3.3V sig-

nals of the UNIT to 5V signals of the UNIT-BUS. The UNIT-BUS Expander is used to distribute the

I2C bus signals SDA and SCL and the UART signals RxD and TxD. In addition, the +5V supply and

GND pins. The Expander can can be mounted in your application with its outer mounting holes (hole

diameter: 2.5 mm).

When using C-Control I extension modules please study the documentation of the C-Control exten-

sion modules. You can find there more technical information on the individual products. Unless

stated otherwise, all expansion modules are supplied with the required operating voltage via their re-

spective connectors on the base unit. Because depending on the application, the cable length can

vary, we offer you these components for self-assembly in the following order numbers:

Ribbon cable RM1.27 0.05mm²: Order No. 607237

Pin header connectors 2x3 RM:2.54mm: Order No. 742063

Matching connection cable pre-assembled (length 35cm) Order No. 198876
