48 MHz 32 bit processor - 6x as fast as ATtiny85 (not even taking into account 32-bit speedups).32 KB RAM - 64x as much as 512 bytes on ATtiny85.256KB Flash - 32x as much as 8 KB on ATtiny85.Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit Cortex M0+.Same size, form-factor, and pinout as classic Trinket.Here are some of the updates you can look forward to when using Trinket M0:

Please check out the Trinket M0 CircuitPython guide for a list of capabilities and quick-start code examples - CircuitPython is easier to code but not as low-level and complete as Arduino. When you're done, unplug the Trinket M0 and your code will go with you. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. When you plug it in, it will show up as a very small disk drive with main.py on it. The most exciting part of the Trinket M0 is that while you can use it with the Arduino IDE, we are shipping it with CircuitPython on board. It's just as small, and it's easier to use, so you can do more. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. We've taken the same form factor we used for the original ATtiny85-based Trinket and gave it an upgrade. It's our lowest-cost CircuitPython programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation.

The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power.
