Arduino have announced another micro-controller board based on a new ATmega32u4, this processor also takes care of the serial communications with the host PC negating the need for a separate serial to USB chip.
There are a few other differences between this board and the trusty UNO: -
- A micro USB connector. At last!
- The SPI bus on the ISP connector no-longer uses any IO pins.
- The device will act as a USB keyboard or mouse to the host PC.
- The board is available with or without the headers, without being slightly cheaper.
I looked at some UK suppliers but they were not showing availability until the 11th of June so it might be worth getting your pre-orders in now.
Also there is an update to the Arduino IDE available, this adds support for the Leonardo as well as multiple language support as well as other changes.
