Digispark ATTINY85 ATMEL Micro USB Tiny85 Microcontroller Module for Arduino

Compact Module with an AtTiny85 Microcontroller for Arduino

This compact module with an AtTiny85 microcontroller is designed for projects with a limited number of pins. Equipped with 8 KB of Flash memory and 6 I/O ports, it facilitates the implementation of advanced functions. It features a MicroUSB connector and is compatible with the Arduino IDE.

The module can be powered directly by 5V or from 7V to 35V thanks to its built-in 5V / 500 mA regulator. It supports I2C and SPI interfaces and operates at a clock speed of 16 MHz. The board has 2.1 mm mounting holes and measures 21 mm x 18 mm. The kit includes a 9-pin gold-pin connector and two LEDs: one for the power supply and another for the user, connected to pin 1. This design ensures versatility and performance for a wide range of electronic applications.
