ATTiny2313 Board RS232

Description

This board is a small controller board on which you can build your projects. It is suited for educational use, experiments or prototyping. The board uses the AT2313 microcontroller with a 10Mhz crystal. The board contains the ISP 10-pin connector for in circuit serial programming. It has also a push button reset switch for resetting the microcontroller. The I/O pins of the microcontroller are also available on two ML10 connectors for connecting for example the LCD-Interface board. The power can be connected via the DC connector which has a pin of 1.1mm. The power regulator supplies the microcontroller with the 5V DC power it needs. The DB9 bus connector can be hooked to the serial port of your PC for communication between the microcontroller and the PC. The MAX232 IC takes care of the voltage conversion of the RS232 voltage levels and the micrcontroller voltage levels.

Programming

The microcontroller on the board can be programmed via the 10-pin ISP connector. The following AT microcontrollers can be programmed with this board:

• ATTiny2313
• AT90S2313 (obsolete)
• AT90S1200 (obsolete)

Connector pinout

In the table below you see the pins of the connectors.

Software

There are several projects on this site that you can try and use with the ISP-board:

• Blink a LED
• LCD@AVR
• LCD Thermometer DS1621
• LCD Themometer LM35
• Real Time Clock
