An Arduino core providing support for nearly all classic ATtiny AVR microcontrollers, including the x4/x5/x61/x7/x8 series, 1634, 828, and x313. It enables programming these chips via ISP, serial (Optiboot), or VUSB (Micronucleus) with the standard Arduino toolchain.
Use cases
- program an ATtiny85 with the Arduino IDE
- flash Arduino sketches to ATtiny 1634 or 828 microcontrollers
- use Arduino APIs on classic tinyAVR chips
- upload firmware to ATtiny via ISP or Optiboot bootloader
- develop embedded projects on ATtiny x4, x41, x5, x61, x7, or x8 parts
- program ATtiny over USB with Micronucleus/VUSB
When to choose
- you need Arduino support for classic ATtiny AVR chips not covered by official cores
- you want ISP, serial, or VUSB programming options for tinyAVR devices
- you are maintaining or building projects on legacy ATtiny hardware
When to avoid
- you are using modern tinyAVR 0/1/2-series chips - use megaTinyCore instead
- you need AVR chips with more features - use DxCore for megaAVR/AVR-Dx parts
- you expect frequent new features - this core is in maintenance mode with only bug fixes
