Digispark ATTINY85 USB Microcontroller Development Board

Description

The Digispark ATTINY85 USB Development Board delivers significant capability in a miniature footprint. Similar to Arduino boards in concept but optimized for smaller, more focused projects, it integrates the ATtiny85 microcontroller, offering an 8-bit AVR architecture operating at up to 20MHz. This board is ideal for developers seeking a minimalist platform for quick prototyping, embedded sensing, or controlling simple devices where space and cost are critical factors.

Programming the Digispark is streamlined via its onboard USB port, utilizing the Micronucleus bootloader and a specialized Digispark core within the Arduino IDE. This setup enables developers to upload sketches directly without external programmers. With 8KB of Flash memory for code, 512 bytes of EEPROM for non-volatile data, and 512 bytes of SRAM for runtime data, the ATtiny85 provides ample resources for a wide range of compact applications. Its peripheral set includes a versatile Universal Serial Interface (USI) that can function as SPI or I2C, alongside multiple ADC channels and PWM outputs, providing essential connectivity for various sensors and actuators.
