What can it do

The Micro45 development board can do most things a regular Arduino Uno can do, but with a smaller form factor.

Additional information/Everything else you need to know

This board was designed with a purpose to create a small microcontroller that was powerful enough to fit demanding projects, have a small amount of I/O pins for smaller projects, easy to power (with a USB connector), easy to program by the ISP pins, and most importantly easy to use. Additionally, this board was made to be extremely small while still packing important features that most development boards at this size/price range lack.

The board is breadboard friendly so pop it into any breadboard for easy prototyping. The board is high quality with a white finish, and professional silk screen to easily understand what pins are where.

Finally, USB functionality is untested/in a beta (limitation being the pcb itself), it is just there as an extra feature/as a bonus! Feedback about this would be appreciated and going forward this feature will be implemented properly! apologies for any inconvenience this may cause.

Plans for the future?

More colors/chip options such as the attiny25/85 when it becomes available again!

Happy making!
