This listing is for bare PCB only. You have to purchase and solder all components your self! This product is recommended for advance users only.

NOTE: THIS BOARD DOES NOT HAS ANY BRAND OR MANUFACTURER NAME PRINTED ON IT! SO IT IS IDEAL FOR RESALE, USED BY TRAINING INSTITUTES OR IN COLLEGE PROJECTS

Parts of the Development Board

atmega8 avr development board parts

  • Power In - Standard DC socket for powering the board. Use a 12v 1A adapter with Center positive pin.
  • 5v & ground -When you attach some other peripheral to the development board, this point can be used to supply that peripheral with regulated 5 volts.
  • 12v Output - Same as above, but 12v for bigger loads like motor or relays. On/Off Switch - Main Power Control, used to turn on/off the entire board.
  • Power Indicator - This glows when board is receiving power from adapter.
  • ISP Header - This is used to update the program of the MCU without removing it from the board.
  • Free Proto Area - Here you can add more components to the board as required by your application. You can then connect them to the i/o ports. 5v and GND are available nearby to power your extra devices. For example you may connect LEDs, Motor Driver etc. in this free area.
  • MCU - ATmega8 Microcontroller.
  • Reset - Resets the MCU, and execution of program is restarted from beginning.
  • Crystal - This is like the heart for MCU. It provides beats that makes the MCU take steps. For accurate timing in you application you need a crystal oscillator. It provides a voltage and temperature independent clock source.
  • I/O Ports - They connect the MCU to the external world, all the peripherals are connected using these i/o ports.
