Atmega32 Mini Development Board Hand Made

Introduction: Atmega32 Mini Development Board Hand Made

About: DIY projects

To implement any project we have some space constraints. So keeping in mind I made a small handy board.

I am using in robot, fan regulator, etc and many places whenever it needed.

Atmega32 IC Details:

• High-performance, Low-power AVR® 8-bit Microcontroller
• Advanced RISC Architecture – 131 Powerful Instructions – Most Single-clock Cycle Execution – 32 × 8 General Purpose Working Registers – Fully Static Operation – Up to 16 MIPS Throughput at 16 MHz – On-chip 2-cycle Multiplier • High Endurance Non-volatile Memory segments – 32 Kbytes of In-System Self-programmable Flash program memory – 1024 Bytes EEPROM – 2 Kbytes Internal SRAM – Write/Erase Cycles: 10,000 Flash/100,000 EEPROM – Data retention: 20 years at 85°C/100 years at 25°C(1) – Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation – Programming Lock for Software Security • JTAG (IEEE std. 1149.1 Compliant) Interface – Boundary-scan Capabilities According to the JTAG Standard – Extensive On-chip Debug Support – Programming of Flash, EEPROM, Fuses, and Lock Bits through the JTAG Interface • Peripheral Features – Two 8-bit Timer/Counters with Separate Prescalers and Compare Modes – One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode – Real Time Counter with Separate Oscillator – Four PWM Channels – 8-channel, 10-bit ADC 8 Single-ended Channels 7 Differential Channels in TQFP Package Only 2 Differential Channels with Programmable Gain at 1x, 10x, or 200x – Byte-oriented Two-wire Serial Interface – Programmable Serial USART – Master/Slave SPI Serial Interface – Programmable Watchdog Timer with Separate On-chip Oscillator – On-chip Analog Comparator • Special Microcontroller Features – Power-on Reset and Programmable Brown-out Detection – Internal Calibrated RC Oscillator – External and Internal Interrupt Sources – Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby and Extended Standby • I/O and Packages – 32 Programmable I/O Lines – 40-pin PDIP, 44-lead TQFP, and 44-pad QFN/MLF • Operating Voltages – 2.7V - 5.5V for ATmega32L – 4.5V - 5.5V for ATmega32 • Speed Grades – 0 - 8 MHz for ATmega32L – 0 - 16 MHz for ATmega32 • Power Consumption at 1 MHz, 3V, 25°C for ATmega32L – Active: 1.1 mA – Idle Mode: 0.35 mA – Power-down Mode: < 1 μA

Step 1: Components Required for Making the Board

most basic things are:


1) vero board

2) soldering material/wire

3) soldering iron

4) DC socket

5) ic 7805 for 12v to 5v dropping

6) 40 pin ic socket

7) Ceramic capacitor (non-polar) 22pf

8) 100mf/16v capacitor

9) 10 pin socket

10) led red or green


12) DC WIRE for connection

13) buzzer (5v) optional

14) .1mf ceramic capacitor

15) 330Ohms resistance

Step 2: Circuit Diagram

I have used internal Oscillator(8 MHz max.).
