Newest Trinket and smallest Lithium Ion

[wxmike]

Hello, i'm not sure this post goes here..

What is the newest trinket board or smallest board and what is the smallest Lithium Ion battery ? I need to power bright led for 30 mins or more.

Thank you

The newest Trinket is the Trinket M0:

The "smallest" board is probably the QT Py. It comes with various processor options, including the same one used on the Trinket M0:

Note that this is not necessarily the most powerful or up to date processor option. Checkout all QT Py options here:

There's also a lipo add on for QT Py:

The smallest lipo is probably the 100mAh one:

Thank you.

What would be the brightest (Single) LED that I can run off the QT Py?
