Summary of ATmega64 Development Board
This Atmel ATmega64 development board offers a robust platform for custom AVR firmware and microprocessor education, surpassing breadboard setups with organized PCB headers. Designed before Arduino's local availability in the Czech Republic, it integrates essential modules like an RTC, temperature sensor, EEPROM, and USB converter. The board supports LCD and 7-segment displays, features PWM control via an N-FET, and includes ISP programming capabilities for efficient testing and debugging of embedded systems.
Parts used in the Atmel ATmega64 Development Board:
- Atmega64 Microcontroller
- DS3231 RTC Real-time IC
- DS1820 1-Wire Temperature Sensor
- 24AA00SN I2C EEPROM
- FT232RL USB/RS232 Converter
- 8x Buttons
- 16x LED Lights
- LCD Display 16×2 Connector
- 7-segment-LED Display
- N-FET for PWM
- ISP Programming Connector J2
- Voltage Regulator
This project is a development board for Atmel ATmega64 microcontroller and can be used to easily develop custom AVR firmware or as an introduction board to microprocessors and programming. A development board is better to be used instead of a breadboard setup as it facilitates the connection of the different components using PCB headers. The project was designed at the time when the Arduino board wasn’t available in the Czech Republic and is equipped with different modules.
Description
The features of this board are:
- Atmega64 – all the ports available through pins, a different crystal can be connected (optional frequency crystal)
- DS3231 RTC, real-time IC / I2C
- Temp. DS1820 1wire Temp. sensor
- EEPROM 24AA00SN / I2C EEPROM
- USB Port FT232RL USB/RS232 converter
