Description
Apart from the powerful CPU, this small microcontroller is also excellent in many other functions. It has 14 PINs which can be used for 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface and 1 SPI interface.
Features:
- Our microcontroller is equipped with a USB Type-C interface that can be used to power and program the controller. On the back side there are additional useful pads for power supply. The module is also equipped with a power LED and a programmable LED.

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.
