Simple 89S52 Project Board

Board has been developed by Wichit Sirichote. It can be used as general purpose development board for various project. For example author have used it for temperature, AC outlet, current measurements with additional current to voltage circuit connected to ADC input.



Board itself has 2x12bit ADC inputs, 4-digit seven segment LED indicator, connector for alphanumeric LCD, four switches, 16 I/O port pins for digital data communication and ISP adapter (89S series allows ISP programming). There are couple example programs like temperature sensor reading through ADC input. So it may be practical board to have or simply to learn 89S52 microcontrollers.
