Useful elements:
This minimalist controller is a new development that is Ideal for rapid prototyping. Thanks to the integrated USB client function, the controller can send keyboard inputs and is therefore suitable as a replacement for the Digispark.
New approach
Normally, a development board of this size uses the chip’s internal crystal oscillator for time fixing. To make the clock more accurate, this microcontroller also applies 32.768 KHz to make the clock more stable.
