Datasheet

Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins,

more FLASH, and more RAM. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash,

and 2K of RAM.

Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. We also added

Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and

friends.
