This project was created on 12/27/2020 and last updated 16 days ago.

Description

Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to +/-2% or better. There are a few ways to perform this manual calibration, but several steps are required. The TinyCalibrator does this fully automatically by a push of a button. In order to make the device more versatile, a high-voltage fuse resetter was also integrated, with which "bricked" ATtinys can be reset to the factory state.Description and project files: https://github.com/wagiminator/ATtiny84-TinyCalibrator

Great one, I could use it.  I made minor changes to my board: jumper 5v and omitted the 3.3v regulator and its 2 capacitors.  I haven't needed to use any of my ATtiny x5 in low voltage, always used 5v

Thank you. Many of my projects are powered directly by batteries. That's why 3.3V makes sense for me.

Can you sell them?

  Are you sure? yes | no

Unfortunately, I don't have the time to make and sell a meaningful amount of boards.

  Are you sure? yes | no
