I’ve been playing around with alternative layouts to the popular Arduino project. Here is one I got in my recent batch of PCBs. It comes as a kit, to be assembled by the customer.
It has basically the same parts as the original: an ATmega168 and 16MHz crystal, 9V DC jack, 5V power supply, power LED, a red LED connected to pin 13, a programming header and a reset button.
But, it doesn’t have a USB jack, as the chip is really tough to solder. Instead you can use a USB-ttl cable (available from Mouser) or a USBmini type thing:
The nice thing about it is that you can plug it into a $3 solderless breadboard and it will be about $20 for a kit. The sad part is you can’t use shields and a separate USB connection.
It will be interesting to see whether the new layout will be useful to people!
