OPEN-SMART Mini ATmega8 board is a development board based on ATmega8A.
You can supply the system voltage as needed, like 3.3V or 5V, which is very useful if you want to set the system to 3.3V to save power.
For example, you want to connect directly 3.3V LCD / ESP8266 wifi / BME280 barometric sensor module to Arduino without level conversion module, you can supply 3.3V to use them directly.
We have used the motherboard and Arduino-1.6.5 IDE to test available peripheral modules as follows:
Touch sensor, eagle eyes LED, buzzer, I2C 1602 LCD, serial MP3 player, serial Bluetooth, long range RF 433MHz kit, DS1307 RTC, etc.
Features:
- Arduino IDE Board Type: OPEN SMART ATmega8, you just need to add the follow 17 lines at the end of the doc ...\arduino-1.6.5-r2\hardware\arduino\avr\ boards.txt. Save it and and then restart the IDE.
