Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and you have your own on the digispark wiki. Arduino compatible Attiny85 Digispark board features:
- USB power supply
- External power supply (7v-35v DC 12v maximum recommended)
- 5V DC 500mA regulator on board
- Programmable with the Arduino IDE
- Loaded with Micronucleus bootloader
