The ATTINY85 USB High Quality Development Board (Digispark style) is an ultra-miniature, low-cost microcontroller breakout board designed for projects where physical footprint and low power consumption are critical. Powered by the Microchip ATmega/ATtiny85 8-bit AVR microcontroller running at 16.5 MHz, this board packs core microcomputing capabilities into a package barely larger than a postage stamp.
Equipped with a Micronucleus VUSB bootloader, the board plugs directly into a standard USB Type-A port or Micro-USB interface for software uploading and power without requiring external FTDI programmers or ICSP hardware. It features an onboard 5V 500mA LDO voltage regulator accepting raw external DC input (7V to 12V DC on the V_IN pin) or regulated 5V power via USB.
Despite its tiny size, the board breaks out 6 General Purpose I/O pins (P0 - P5) supporting PWM output, 10-bit Analog Inputs (ADC), I2C, and SPI communication. It is fully compatible with the Arduino IDE via Digispark board support packages, making it an ideal choice for custom USB HID devices (digispark keyloggers/macro pads), wearable tech, compact IoT nodes, and simple automation setups.
