2.1.8 Mega32 Projectboard

The C-Control Projectboard PRO32 (Conrad Item no. 197287) provides a economic alternative to the

application board MEGA32 (Conrad-Order no. 198 245). Compared to the C-Control Pro application

board, it's range of functions is significantly limited, and is used mainly for own hardware develop-

ments related to the MEGA32 UNIT. The Projectboard includes the most important components

needed to operate the MEGA32 UNIT. Furthermore, the Projectboard features a power supply (USB /

AC adapter), a interface converter (RS232) and a large prototype area available for own development.

By default, the Projectboard is designed for programming via RS232. Optionally, the RS232-USB

converter (Conrad-Order no. 197 257) can be used for programming the MEGA32 UNIT via USB. In

this case the programming is done via the serial connection of the MEGA32 UNIT (UART), so the

program transfer is not as fast as the USB transfer on the application board MEGA32.

The MEGA32 UNIT is so plugged that the signature of the UNIT is readable, if the programming

and power connectors show out to you.

In the baseline condition with no-USB-RS232 converters the jumpers J4/J3 are put like shown in

the figure.

When using the RS232-USB converter (not included), the jumper must be reconnected to USB.

The jumper J2 is used to select the supply voltage. With the jumper set to "network", the clamps

J11 are used for the power supply (stabilized DC power supply or power adapter min. 100mA, de-

pending on application). If the jumper J2 is replugged to USB, the board can be operated via the

USB power supply of the computer.

Attention! A maximum current of 100mA through USB should not be exceeded!
