Description
This board is very similar to Arduino Pro Mini and it is 100% compatible on software level. However, there are some minor differences.
Board uses ATmega 328P-mu microcontroller which has the same core as original Arduino's ATmega 328P-AU, but in different package
The power IC of this board is AMS1117. The max input voltage of this IC is 15V DC while the original board is 12V. The max output current of this IC is 800mA while the original board is 500mA.
Note: The max output current is influnced by the working temperature. If necessary, add a heatsink.
- Microcontroller: ATmega328P-MU
- Operating Voltage: 3.3V
- Input Voltage: 2.7V -15V 1
- Digital I/O Pins: 20
- Analog Input Pins: 8
- Clock Speed: 8 MHz
- Dimensions: 33.3 x 18.0 mm
1 Board will not work when voltage drops below 2.7V. If you are supplying power below 5V you may conect it to VCC pinc. If you're supplying unregulated power to the board above 5 volts, you must connect it to the "RAW" pin, not VCC.
