SPIDER Automation Digispark ATtiny85 Mini USB Development Board | ATtiny85 Microcontroller
Description
SPIDER Automation Digispark ATtiny85 Mini USB Development Board is small in size yet packed with capabilities. Designed as an affordable and compact alternative to traditional Arduino boards, it provides full compatibility with the familiar Arduino IDE and can be programmed directly via USB without needing any external programmer.
Built around the high-performance, low-power Atmel ATtiny85 8-bit microcontroller, the board operates up to 20MHz (at 4.5–5.5V) and features 8KB of Flash program memory, 512 bytes of EEPROM, and 512 bytes of internal SRAM. Fully assembled (with included uninstalled Berg headers for custom configuration), it represents the ultimate entry point into microcontroller electronics and permanent project embedding.
Key Features
- ATtiny85 8-Bit Microcontroller: Low-power AVR core featuring 8K Bytes of In-System Programmable (ISP) Flash memory.
- Direct USB Connectivity: Plugs straight into a USB port for rapid code flashing and power supply.
- Arduino IDE Compatible: Fully supported by standard Arduino core libraries for effortless software development.
- Versatile I/O Peripherals: Breaks out up to 5 GPIOs, 4 single-ended 10-bit ADC channels, 2 high-frequency PWM outputs, and a Universal Serial Interface (USI supporting I2C and SPI).
- Low Power Consumption: Engineered for efficient active and standby modes across a 2.7V to 5.5V operating window.
- Compact Form Factor: Ultra-small 21mm × 18mm dimensions make it ideal for space-constrained projects.
Benefits
- Cost-Effective Prototyping: Inexpensive enough to leave permanently soldered inside finished DIY builds and custom enclosures.
- No External Programmer Required: Onboard USB connectivity eliminates the need for separate ISP programmers or USB-to-serial adapters.
- Rapid Learning Curve: Familiar Arduino environment lets beginners and pros jump straight into microcontroller development.
Applications
- Compact IoT Devices: Miniature sensor nodes and wireless peripheral controllers.
- Wearable Electronics: Low-profile microcontroller integration for smart garments and accessories.
- USB Gadgets & HID Devices: Custom keyboard shortcuts, macro pads, and USB dongle prototyping.
- Automation & Hobbyist Prototyping: Quick automation tasks requiring a small footprint and low component count.
