## Description

This demo board by Sure Electronics is a low cost development tool to learn the ATMEGA16 architecture and the onboard high performance peripherals.

The board is populated with one ATMEGA16 IC, a 20\*2 character LCD, four digits 7-segment LED display, three tactile switches, LM75 I2C digital temperature sensor, a USB mini-B socket, a buzzer, 10-pin IDC connector and LED indicators. Powered via USB mini-B socket, several program functions including temperature measurement, backlight adjustment and contrast adjustment, are selectable via a menu system displayed on the LCD. Both LCD and 7-segment LEDs can be used to display current temperature in ℃ and ℉. In addition, connecting this demo board and PC with a USB cable, you can also see more detailed information via Hyper Terminal.
