MikroElektronika
AVR-Ready1™
Manual
All Mikroelektronika’s development systems feature a large number of peripheral
modules expanding microcontroller’s range of application and making the
process of program testing easier. In addition to these modules, it is also
possible to use numerous additional modules linked to the development system
through the I/O port connectors. Some of these additional modules can operate
as stand-alone devices without being connected to the microcontroller.

AVR-Ready1 Additional Board
The AVR-Ready1 additional board enables a .hex code to be quickly and easily loaded into AVR microcontrollers by
using the AVRprog programmer. The additional board is supplied with two sockets for AVR microcontrollers in DIP40
package, 2x5 male connectors connected to the microcontroller pins, pads, srew terminal for power supply, USB
connector and reset button.
Key features:
- Data transfer via USB-UART communication;
- Programming via the external programmer;
- Pads;
- 8 to 16V AC/DC power supply voltage;

How to connect the board?
The AVR-Ready1 board features ve 2x5 connectors (CN1 - CN5) that enable connection between the pins of the
microcontroller plugged into the appropriate socket on the board and external devices. A 2x5 connector CN6 is used to
connect the AVRprog programmer to the microcontroller pins used for programming. A USB connector CN51 enables
connection between the additional board and a PC via the UART module. In order to enable USB-UART communication,
it is necessary to place jumpers J1 and J2. By doing this, the RX and TX pins of the USB-UART module are connected
to the appropriate pins of the microcontroller. The additional board is powered with voltage in a range between 8 and
16V AC/DC via the CN8 connector.
How to use the board?
In order to use the AVR-Ready1 additional board, it is rst necessary to place a microcontroller in DIP40 package into
the appropriate socket supplied on the board. The microcontroller is programmed with the AVRprog programmer that is
plugged via its IDC10 connector into a 2x5 connector CN6 supplied on the board. In order to reset the microcontroller,
just press the RESET button.
