ATTINY85 Digispark Development Board

Microcontroller Core: Powered by the 8-bit ATtiny85 AVR processor running at 16.5 MHz with 8KB Flash memory, 512 B SRAM, and 512 B EEPROM.

Onboard Micro-USB Interface: Features an integrated Micro-USB port for seamless direct connection to laptops and PCs for power delivery, debugging, and code uploading.

6 General Purpose I/O Pins: Breaks out 6 GPIO pins supporting PWM outputs, 10-bit ADC analog inputs, and software-based I2C/SPI serial communication protocols.

Flexible Dual-Power Architecture: Powered directly via 5V Micro-USB input or through external 7V–12V DC sources via the onboard voltage regulator.

Arduino IDE & Micronucleus Bootloader Support: Pre-flashed with the Micronucleus bootloader for fast code deployment directly through the standard Arduino IDE software environment.

Module Construction: Built on a double-sided FR-4 glass epoxy printed circuit board featuring surface-mount components and standard 2.54 mm header solder pads.

Operating Voltage & Logic: Runs logic circuitry on 5V DC. Ensure connected sensors and input lines conform to 5V logic thresholds.

Handling Precautions: Hold carefully by the outer circuit board edges. Exercise electrostatic discharge (ESD) care when handling raw circuit components.

Environmental Limits: Operating temperature range spans -40°C to +85°C. Keep protected from static discharge, conductive metal dust, and liquid moisture.

Ultra-Compact Digispark Platform: Position as an iconic, budget-friendly micro-board for deploying space-constrained automation nodes, DIY USB peripherals, and mini IoT setups.

No Programmer Required: Highlight the onboard Micro-USB interface that allows makers to program the board straight out of the box without requiring external ISP programmers.

Recommended Cross-Sell Add-ons: Pair with Micro-USB Cables, Solderless Breadboards, Dupont Jumper Wires, and 5V Relay Modules.

Ideal for Niche Physical Computing: Perfect choice for building custom USB HID macro keys, status indicator lights, small sensor loggers, and automated switch triggers.
