ATTINY85 Digispark kickstarter mini USB Development Board The ATTINY85 Digispark Kickstarter Mini USB Development Board is a compact and cost-effective microcontroller platform based on the ATTINY85 chip. Designed for simplicity and versatility, it offers seamless integration with the Arduino IDE (version 1.0 ), making it accessible for both beginners and experienced developers. This board features a built-in USB interface, eliminating the need for external programmers. It can be powered directly via USB or through an external source ranging from 7 to 35V, thanks to its onboard 500mA 5V regulator. With 6 I/O pins (2 of which are shared with USB functionality), 8KB of flash memory (approximately 6KB available after bootloader), and support for I2C and SPI communication protocols, the Digispark board is well-suited for a variety of applications, including wearable devices, sensor projects, and compact automation systems.
