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

We're no longer selling this pack of Pro Trinket 3V+5V, we recommend our Metro Mini (5V 328P with USB-Serial Converter), Feather 328P (3.3V 328P with USB-Serial and LiPo charger), ItsyBitsy 32u4 (Available in both 3.3V and 5V) and the ItsyBitsy M0. The Metro Mini and Feather 328p both use the same ATmega328P chip, but come with a real USB-serial converter chip. The ItsyBitsy boards have 'native' USB and are almost the same size. None of these boards are perfect drop-in-compatible with all the pins in the same location, but they all have equivalent or improved capabilites!
