runtimeprojects.com has a quick review of the Digispark board. It’s a really interesting mini board that can be used in small projects using Arduino IDE.
In today’s blog post we’ll analyze one of the smallest and most practical boards out there. The Digispark board. It’s size, including the USB port, is 25mm x 18mm (so tiny)!! This little board is powered by an ATTINY85 chip and clocked to 16.5Mhz. For conveniece, it has a built in USB port and can be plugged into a your computer without cables or adapters. Now that’s pretty awesome! It is powered by either the USB port, from the +5v pin with regulated 5v or from VIN pin if unregulated. The VIN pin supports from 7v to 35v although less than 12v is recommended by the manufecturer.
