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.

Frequently Asked Questions

How is the Digispark ATtiny85 programmed?

The Digispark ATtiny85 is programmed directly via its integrated USB port. It uses the Micronucleus bootloader and can be programmed using the Arduino IDE after installing the Digispark board support package. No external programmer is typically required, simplifying the development workflow for makers and engineers.

What are the power requirements for the Digispark ATtiny85?

The Digispark ATtiny85 board is designed to be powered directly from a 5V USB connection. While its internal ATtiny85 microcontroller can operate across a voltage range of 2.7V to 5.5V, the board's components are optimized for 5V operation, commonly provided by a computer USB port or a USB power adapter.

What communication interfaces does the ATtiny85 offer?

The ATtiny85 features a Universal Serial Interface (USI) which is a flexible hardware module that can be configured to act as an SPI master/slave, I2C master/slave, or a 1-Wire interface. This allows for communication with various peripherals like sensors, displays, and other microcontrollers, making it versatile for compact projects.

What are the memory specifications of the ATtiny85?

The ATtiny85 microcontroller on the Digispark board provides 8KB of In-System Programmable (ISP) Flash memory for storing program code, 512 bytes of EEPROM for non-volatile data storage that persists across power cycles, and 512 bytes of internal SRAM for dynamic data during program execution. These resources are suitable for many small-scale embedded applications.
