A simple low cost development board for experimenting with Atmel's popular ATmega8A microcontroller. It can be powered from an external 5V power supply, or via a USB port using a mini USB cable (not supplied). The board also has a convenient ISP header which is compatible with most ISP programmers including our USBTinyISP (ARDU0002).
1. Microcontroller chip? ATmega8
2. MiniUSB interface or pin power supply, on-board AMS1117-3.3 chip, jumper sets supply voltage to 3.3V or 5V.
3. On-board crystal oscillator, external crystal with 8M by default.
4. All the IO port are leaded out and marked.
5. On-board ISP interface.
6. Reliable reset circuit.
7. AD converter reference voltage with filter inductor and capacitor.
