ATmega 328PB microcontroller board with 3V logic
The ARD-Nanov4-3V-MC is a particularly small microcontroller that has been specially developed for use with breadboards thanks to its downward-facing pin header. The integrated USB Type-C interface can be used to supply power to both the circuit and the board, as well as to transfer programs to the microcontroller. The logic level, which is 3.3V by default, can be easily changed to 5V using a solder bridge. The board has 2 additional IO pins and an additional hardware I2C and SPI interface (compared to the ARD Nano V4 3V). The bootloader used is compatible with most existing Arduino libraries.
In addition, the board has a high-precision clock generator that is optimized for demanding applications and precise time measurements. Clock frequency 8 MHz, deviation of the external clock (at room temperature) ±10ppm (±0.001%), logic level 3.3 V / 5V switchable via solder bridge, 8 analog pins, 14 (including 6 PWM) digital pins.
