Compact ATmega32 board with many on-board features This AVR board is a good choice for experiments, training and various projects.
ATmega32 Development Board Features
Note: Standard USB cables have a Type-A connector on one end and a Type-B connector on the other. The Type-A connector plugs into your computer or USB hub and the Type-B connector plugs into a USB peripheral. This board has a Type-A connector. Consequently, you will either need a Type-A to Type-A USB cable, or alternatively a Type-B to Type-A USB adapter that allows you to use a standard USB cable. We offer such an adapter as an optional add-on item below.
- 4 LEDs
- 2 Pushbuttons
- 4x4 Keypad (Keypad is on-board)
- RS232 Interface
- Buzzer connected to AVR timer PWM output
- Real-Time Clock DS1307 connected via I2C
- Socket for RTC battery backup (CR2032 battery not included)
- 24C256 EEPROM connected via I2C
- LM35 Temperature sensor connected to ADC of ATmega32
- Light sensor (LDR) connected to ADC of ATmega32
- Potentiometer connected to ADC of ATmega32
- RC5 IR receiver
- 16x2-character LCD
- 2x5 JTAG connector
- Single row, 6-pin ISP connector (cable with flying leads included)
- On-board Reset switch
- Type-A USB connector for powering the board.
ATmega32 Development Board Power Sources
- Power from USB (the USB connector on the board has no other functionality; it is used only to supply +5V to the board)
- Regulated 4.5V-5V DC power supply connected to a 2-pin male header.
Note: Any voltage higher than 5V DC, or use of an unregulated power supply, can damage the board. The board has no on-board voltage regulator. If you don't have a regulated 5V supply, a no-solder solution is to get the MIKROE-192 voltage regulator/rectifier and connect a couple of wires between its 5V output screw terminals and the power pins on the AVRLiPV2. Then you can use the 9V or 12V setting on the WA-VAR-US or WA-UNI power supply plugged into the MIKROE-192.
Note2: This board does not connect the AREF, AGND and AVCC pins of the ATmega microcontroller. The reason for this is to give you the ability to add a low-pass filter between digital Vcc and analog Vcc if desired and to provide you with the option to use an Aref and AGND level that are different from DVcc and DGND. However, before using this board we highly recommend that you tie those pins to a defined signal level (for example AVcc and Aref to DVcc and AGND to DGND), even if you do not intend to use the chip's A/D converter. Leaving those pins floating may result in functional failure.
