The Wattuino Pro Mini is a small Arduino clone with ATmega328 and runs at 3.3V with 8MHz.
All components are mounted on the board except for the connectors, but they are included.
To program the board you need an USB TTL adapter or a FTDI Breakout, because the board itself has no USB port.
Advantages over the Arduino mini pro:
- all pins with 2.54 mm pitch
- all pins of the AVR are available (also ADC6, ADC7)
- LC-filter on AVCC of the AVR
- pin headers are included (but not soldered)
Features:
- ATmega328 @ 8MHz (external resonator)
- compatible with Arduino pro mini
- 3.3V voltage regulator with max. 150mA output
- Size: 18x33mm
- DC input 3.3V - 12V
- Made in Germany
