ATTiny85 USB Development Board, I2C and SPI Ready Microcontroller Module for Arduino Projects

ATTiny85 USB Mini Development Board with I2C and SPI support Overview A compact ATTiny85 based USB development board designed for small projects and rapid prototyping. Provides USB connectivity, multiple I O lines, analog inputs, PWM outputs, and flexible power options in a 26.4 mm form factor. Key benefits Small footprint for space constrained applications and wearable or embedded projects. Built in USB for easy programming and optional USB communication and debugging. Flexible power: accepts USB power, external power, or a 7 to 16 V input with automatic regulation to 5 V. Ready for common embedded interfaces: I2C and SPI available via the USI hardware. Low component overhead makes it suitable for battery powered projects and short development cycles. Features and specifications Microcontroller: ATTiny85 Flash memory: 8 KB total, about 6 KB available after bootloader Digital I O: 6 pins total; two pins are shared with USB functions and are available unless USB communication is actively used Analog inputs: ADC on 4 pins PWM: hardware PWM on 3 pins; additional PWM possible using software routines Communication: I2C and SPI supported via USI USB: built in USB interface for programming and device communication Power: USB power, external power, or 7 V to 16 V input with automatic selection and regulation Regulator: onboard 150 mA 5 V regulator Indicators: power LED and test LEDs Material: ABS Size: approximately 26.4 mm length Software: compatible with IDE 1.0 and later on Windows, OSX and Linux What is included 1 x ATTiny85 USB development board Practical applications USB HID device prototyping such as custom keyboards or simple input devices using the built in USB interface Compact sensor nodes that use I2C sensors and analog inputs for portable monitoring Small robotics or actuator projects that use PWM outputs for motor or servo control Embedded control in consumer prototypes, wearables, or educational electronics projects Notes Allow a measurement tolerance of up to 0 to 1 cm due to manual measurement. Actual product color may vary slightly from images due to display differences.
