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.
