Adafruit Pro Trinket 6-Pack - 3 x 3V and 3 x 5V Trinkets

Discontinued

Note: The Pro Trinket's bit-bang USB technique is a legacy approach. For new projects, consider boards with native USB support such as the ItsyBitsy 32u4 or ItsyBitsy M0.

The Adafruit Pro Trinket 6-Pack is a value bundle containing three 3V and three 5V Pro Trinket boards. Each Pro Trinket is a compact ATmega328P-based microcontroller with 18 GPIO pins, 28 KB Flash, 2 KB RAM, and Micro-USB connectivity — packing Arduino UNO-level capability into a 1.5" × 0.7" form factor.

What's Included

  • Pro Trinket 3V – ATmega328P at 3.3V / 12 MHz for lower-power projects
  • Pro Trinket 5V – ATmega328P at 5V / 16 MHz, same speed and voltage as Arduino UNO

Key Features (Each Board)

  • ATmega328P Processor – Compatible with 99% of Arduino sketches
  • 18 GPIO Pins – Including analogue inputs (pins 2 and 7 reserved for USB)
  • 28 KB Flash / 2 KB RAM – 28,672 bytes available for sketches
  • Micro-USB + FTDI Header – Dual programming options
  • On-Board Voltage Regulator – 150 mA output with up to 16V input, reverse-polarity and thermal protection
  • Auto Power Switching – Seamless USB-to-battery switchover
  • Mounting Holes – For secure installation

Ideal For

  • Workshops, classrooms, and maker events
  • Multi-board projects requiring both 3.3V and 5V variants
  • Stocking up on compact Arduino-compatible boards
