89S52 Development Board

89S52 Development Board is a compact development board equipped with USB port for direct connectivity with latest laptops and PCs. When connected to PC / Laptop, board does not need additional power supply and can function from supply through USB.

AT89S52 is microcontroller from Atmel having 8KB flash memory soldered on this board with 11.0592MHz crystal. 89S52 is in-circuit-programmable chip and thus does not need to be removed from board for programming. The board is also equipped with many additional accessories such as Buzzer, RTC, 64KB EEPROM, provision for character LCD alongwith contrast adjustment potentiometer and backlight on-off control. Two ports (Port 1 & 2) are available on berg connectors for extended connectivity and usage.

The board is designed to correctly align with 20x4 LCD to right size and thus it can also act as a LCD backpack.

Features

• This board is assembled with almost all the necessary additional components for a small / medium sized project and thus can be directly used for project developments, as-is with minor modifications and program updates
• Compact size / form-factor 98mm x 60mm
• Perfectly fits as a 20x4 LCD backpack (LCD size 98mm x 60mm)
• Onboard USB to Serial converter
• Default powered with USB supply and supports upto 100mA
• Provision for external power supply
• DS1307 based onboard RTC with 32.768KHz crystal & 3V battery socket
• Equipped with 24C64 - 64KB I2C EEPROM
• Buzzer available on Port 3
• INT0 & INT1 pins are extended for interrupt keys with onboard pull-ups
• ISP header available for programming the microcontroller with external ISP programmer

ATmega168 Development Stick

ATmega168 Development Stick is a very compact development stick equipped with USB port for direct connectivity with latest laptops and PCs. It is also USB powered and does not need additional power supply when connected to PC or Laptop.
