We are happy to present you the new Ardumower mainboard in version 1.4. In the course of time, additional boards have increasingly appeared (undervoltage shutdown, motor driver protection boards, ...). So in the end you had four boards and a lot of cabling. These functions are integrated on the new board so that only this one mainboard is required. Despite the convenient SMD pre-assembly by us, we were able to reduce the price by 5 euros compared to the 4 single boards.
Thanks to the 3.3 V / 5 V compatibility, you now have the option between the Arduino Due (Azurit and Sunray) / Adafruit M4 (Sunray) with 3.3 V or the Arduino Mega (Azurit) with 5 V.choose.
